Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.
I preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:
git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
xargs perl -pi -e \
's/\buninitialized_var\(([^\)]+)\)/\1/g;
s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'
drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.
No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,
alpha, and m68k.

Ingo suggested that since the new sched_set_*() functions are
implemented using the 'nocheck' variants, they really shouldn't ever
fail, so remove the return value.

Because SCHED_FIFO is a broken scheduler model (see previous patches)
take away the priority field, the kernel can't possibly make an
informed decision.
No effective change.

Pi-Hsun Shih <pihsun@chromium.org>:
Add support for controlling voltage regulator that is connected and
controlled by ChromeOS EC. Kernel controls these regulators through
newly added EC host commands.
Changes from v5:
* Move new host command to a separate patch.
* Use devm_regulator_register.
* Address review comments.
Changes from v4:
* Change compatible name from regulator-cros-ec to cros-ec-regulator.
Changes from v3:
* Fix dt bindings file name.
* Remove check around CONFIG_OF in driver.
* Add new host commands to cros_ec_trace.
* Address review comments.
Changes from v2:
* Add 'depends on OF' to Kconfig.
* Add Kconfig description about compiling as module.
Changes from v1:
* Change compatible string to google,regulator-cros-ec.
* Use reg property in device tree.
* Change license for dt binding according to checkpatch.pl.
* Address comments on code styles.

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Pull i2c updates from Wolfram Sang:
"I2C has quite some patches for you this time. I hope it is the move to
per-driver-maintainers which is now showing results. We will see.
The big news is two new drivers (Nuvoton NPCM and Qualcomm CCI),
larger refactoring of the Designware, Tegra, and PXA drivers, the
Cadence driver supports being a slave now, and there is support to
instanciate SPD eeproms for well-known cases (which will be
user-visible because the i801 driver supports it), and some
devm_platform_ioremap_resource() conversions which blow up the
diffstat.
Note that I applied the Nuvoton driver quite late, so some minor fixup
patches arrived during the merge window. I chose to apply them right
away because they were trivial"

Recycle the ISH buffer before notifying of a response or an event. Often
a new message is sent in response to an event and in high traffic
scenarios this can lead to exhausting all available buffers. We can
ensure we are using the fewest buffers possible by freeing buffers as
soon as they are used.

The ISHTP layer can give us old responses that we already gave up on. We
do not want to interpret these old responses as the current response we
are waiting for.
The cros_ish should only have one request in flight at a time. We send
the request and wait for the response from the ISH. If the ISH is too
slow to respond we give up on that request and we can send a new
request. The ISH may still send the response to the request that timed
out and without this we treat the old response as the response to the
current command. This is a condition that should not normally happen but
it has been observed with a bad ISH image. So add a token to the request
header which is copied into the response header when the ISH processes
the message to ensure that response is for the current request.

this is being passed to 'send_ec_cmd' as type u8, thus, result
is stored in least significant byte. Due to output format,
the whole 'val' value was being displayed when any of the most
significant bytes are different than zero.
This fix will make sure only least significant byte is displayed
regardless of remaining bytes value.

On x86 ChromiumOS devices, the pmsg_size is set to 0 (check
/sys/module/ramoops/parameters/pmsg_size): this prevents use of
pstore-pmsg, even if CONFIG_PSTORE_PMSG is enabled. Set pmsg_size
to a value that is consistent with the size used on non-x86 ChromiumOS
devices.

Pull media updates from Mauro Carvalho Chehab:
- Media documentation is now split into admin-guide, driver-api and
userspace-api books (a longstanding request from Jon);
- The media Kconfig was reorganized, in order to make easier to select
drivers and their dependencies;
- The testing drivers now has a separate directory;
- added a new driver for Rockchip Video Decoder IP;
- The atomisp staging driver was resurrected. It is meant to work with
4 generations of cameras on Atom-based laptops, tablets and cell
phones. So, it seems worth investing time to cleanup this driver and
making it in good shape.
- Added some V4L2 core ancillary routines to help with h264 codecs;
- Added an ov2740 image sensor driver;
- The si2157 gained support for Analog TV, which, in turn, added
support for some cx231xx and cx23885 boards to also support analog
standards;
- Added some V4L2 controls (V4L2_CID_CAMERA_ORIENTATION and
V4L2_CID_CAMERA_SENSOR_ROTATION) to help identifying where the camera
is located at the device;
- VIDIOC_ENUM_FMT was extended to support MC-centric devices;
- Lots of drivers improvements and cleanups.

On the ASUS laptop UX325JA/UX425JA, most of the media keys are not
working due to the ASUS WMI driver fails to be loaded. The ACPI error
as follows leads to the failure of asus_wmi_evaluate_method.
ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [IIA3] at bit offset/length 96/32 exceeds size of target Buffer (96 bits) (20200326/dsopcode-203)
No Local Variables are initialized for Method [WMNB]
ACPI Error: Aborting method \_SB.ATKD.WMNB due to previous error (AE_AML_BUFFER_LIMIT) (20200326/psparse-531)
The DSDT for the WMNB part shows that 5 DWORD required for local
variables and the 3rd variable IIA3 hit the buffer limit.
Method (WMNB, 3, Serialized)
{ ..
CreateDWordField (Arg2, Zero, IIA0)
CreateDWordField (Arg2, 0x04, IIA1)
CreateDWordField (Arg2, 0x08, IIA2)
CreateDWordField (Arg2, 0x0C, IIA3)
CreateDWordField (Arg2, 0x10, IIA4)
Local0 = (Arg1 & 0xFFFFFFFF)
If ((Local0 == 0x54494E49))
..
}
The limitation is determined by the input acpi_buffer size passed
to the wmi_evaluate_method. Since the struct bios_args is the data
structure used as input buffer by default for all ASUS WMI calls,
the size needs to be expanded to fix the problem.

chasis-type
The HP Stream x360 11-p000nd no longer report SW_TABLET_MODE state / events
with recent kernels. This model reports a chassis-type of 10 / "Notebook"
which is not on the recently introduced chassis-type whitelist
Commit de9647efeaa9 ("platform/x86: intel-vbtn: Only activate tablet mode
switch on 2-in-1's") added a chassis-type whitelist and only listed 31 /
"Convertible" as being capable of generating valid SW_TABLET_MOD events.
Commit 1fac39fd0316 ("platform/x86: intel-vbtn: Also handle tablet-mode
switch on "Detachable" and "Portable" chassis-types") extended the
whitelist with chassis-types 8 / "Portable" and 32 / "Detachable".
And now we need to exten the whitelist again with 10 / "Notebook"...
The issue original fixed by the whitelist is really a ACPI DSDT bug on
the Dell XPS 9360 where it has a VGBS which reports it is in tablet mode
even though it is not a 2-in-1 at all, but a regular laptop.
So since this is a workaround for a DSDT issue on that specific model,
instead of extending the whitelist over and over again, lets switch to
a blacklist and only blacklist the chassis-type of the model for which
the chassis-type check was added.
Note this also fixes the current version of the code no longer checking
if dmi_get_system_info(DMI_CHASSIS_TYPE) returns NULL.

Note SW_TABLET_MODE is already reported through the intel_vbtn driver on
this and other Dell devices, so dell_wmi should not report this too,
to avoid duplicate events.

For a long time we have the latter one, thus, replace next_cmd(&buf) with
strsep(&buf, ",").

input-device
Setting the initial state of input-device switches must be done before
registering the input-device.
Otherwise the initial state will get send out as an event as soon
as input_sync() gets called.
E.g. when undocking a tablet using intel-vbtn to report SW_TABLET_MODE
and SW_DOCK before this commit we would get (evemu-record output):
E: 0.000001 0005 0005 0001 # EV_SW / SW_DOCK 1
E: 0.000001 0000 0000 0000 # ------------ SYN_REPORT (0) ---------- +0ms
E: 0.000109 0005 0005 0000 # EV_SW / SW_DOCK 0
E: 0.000109 0000 0000 0000 # ------------ SYN_REPORT (0) ---------- +0ms
E: 0.000133 0005 0001 0001 # EV_SW / SW_TABLET_MODE 1
E: 0.000133 0000 0000 0000 # ------------ SYN_REPORT (0) ---------- +0ms
The first SW_DOCK=1 report is spurious, setting the initial switch
state before registering the input-device fixes this.

This is a preparation patch for calling detect_tablet_mode() from
intel_vbtn_input_setup() without needing a forward declaration.
Note this commit makes no functional changes, the moved block of code
is completely unchanged.
