* gigaset: reduce syslog clutterTilman Schmidt2010-02-261-5/+2
| | | | | | | | | | Improve readability of the Gigaset driver's kernel messages by removing a few unnecessary messages and limiting the emission of some debug messages more narrowly. Impact: logging Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
* bas_gigaset: collapse CR/LF at end of AT responseTilman Schmidt2010-02-261-2/+2
| | | | | | | | | | | | Copy the mechanism from ser_/usb_gigaset to avoid producing spurious empty responses for CR/LF sequences from the device. Add a comment in all drivers documenting that behaviour. Correct an off by one error that might result in a one byte buffer overflow when receiving an unexpectedly long reply. Impact: minor bugfix Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
* gigaset: convert strcmp chain to table lookupTilman Schmidt2009-10-291-6/+0
| | | | | | | | | | Replace the sequence of strcmp calls for interpreting ZSAU parameter strings by a table of known strings and lookup loop to improve readability. Impact: readability improvement, no functional change Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
* gigaset: checkpatch cleanupTilman Schmidt2009-10-291-31/+29

* usb_gigaset: code cleanupTilman Schmidt2009-10-291-8/+5
| | | | | | | | | | Reorganize the code of the Gigaset M10x driver to make it more readable, less redundant, better aligned to the style of other parts of the driver, and cause fewer checkpatch.pl complaints. Impact: code reorganization, no functional change Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
* gigaset: fix bad assumptions about CAPI skbuffsTilman Schmidt2009-10-291-1/+1
| | | | | | | | | | | | | | | | | The CAPI interface incorrectly assumed that CAPI messages would always start at the beginning of the data buffer: fix by treating DATA_B3 messages as the link layer header to their payload data. This fix changes the way acknowledgement information is propagated through the hardware specific modules and thereby impacts the ISDN4Linux variant of the driver, too. Also some assumptions about methods not being called from interrupt context turned out to be unwarranted; fix by using dev_kfree_skb_any() wherever non-interrupt context isn't guaranteed. Impact: bugfix Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
* gigaset: add Kernel CAPI interface (v3)Tilman Schmidt2009-10-061-1/+6
| | | | | | | | Add a Kernel CAPI interface to the Gigaset driver. Impact: optional new functionality Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
* gigaset: prepare for CAPI implementationTilman Schmidt2009-10-061-63/+27
| | | | | | | | | | Reorganize the code of the Gigaset driver, moving all isdn4linux dependencies to the source file i4l.c so that it can be replaced by a file capi.c interfacing to Kernel CAPI instead. Impact: refactoring, no functional change Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
* gigaset: remove unused structure member rcvbytesTilman Schmidt2009-05-171-1/+0
| | | | | | | | | The B channel data structure member rcvbytes was never set to anything else but zero, so drop it. Impact: cleanup Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
* gigaset: remove obsolete references to m10x state tableTilman Schmidt2009-05-171-2/+2
| | | | | | | | | The separation of state tables for base and M10x has long been removed. Clean up remaining traces of it. Impact: cleanup Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
* gigaset: use pr_err() and pr_info()Tilman Schmidt2008-12-261-11/+3
| | | | | | | | | Switch from private printk wrapper macros to using pr_err() and pr_info() from linux/kernel.h, at the same time unifying a few error messages. Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
* gigaset: get rid of info() and warn() macrosTilman Schmidt2008-11-291-6/+0
| | | | | | | | | Join the move away from the obsolete info() macro, opencoding the remaining uses. While we're at it, also get rid of the warn() macro by promoting the three remaining uses to err(). Signed-off-by: Tilman Schmidt <tilman@imap.cc> Signed-off-by: David S. Miller <davem@davemloft.net>
* gigaset: use dev_ macros for messagesTilman Schmidt2008-07-241-3/+0
| | | | | | | | | | | The info() / warn() / err() macros from usb.h for generating kernel messages are considered inferior to dev_info() / dev_warn() / dev_err() from device.h. Replace them where possible. Also correct the severity level and improve the text of one message.

| | | | | | | | | | | Using the class device pointer returned by tty_register_device() with part 1 of the patch, attach the Gigaset drivers' "cidmode" sysfs entry to its tty class device, where it can be found more easily by users who do not know nor care which USB port the device is attached to.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a possible Oops in the Siemens Gigaset base driver when the device is unplugged while an ISDN connection is still active, and makes sure that the isdn4linux link level (LL) is properly informed if a connection is broken by the USB cable being unplugged. - Avoid unsafe checks of URB status fields outside the URB completion handlers, keep track of in-use URBs myself instead. - If an isochronous transfer URB completes with status==0, also check the status of the frame descriptors. - Verify length of interrupt messages received from the device. - Align the length limit on transmitted AT commands with the device documentation. - In case of AT response receive overrun, keep newly arrived instead of old unread data. - Remove redundant check of device ID in the USB probe function. - Correct and improve some comments and formatting.
