The call chain
generic_handle_irq(irq_find_mapping(domain, x));
could be replaced with
generic_handle_domain_irq(domain, x);
which looks up the struct irq_desc for the interrupt and handles it with
handle_irq_desc().
This is a slight optimisation given that the driver invokes only one
function and the struct irq_desc is used directly instead being looked
up via irq_to_desc().
Use generic_handle_domain_irq().

Contrary to what the naming might suggest, devm_regulator_get_optional
returns -ENODEV in case the regulator is not found which will trigger
probe error in this driver.
Use devm_regulator_get instead which will return a dummy regulator that
we can just use as if it was a proper regulator.

ACPI_PTR() is more harmful than helpful. For example, in this case
if CONFIG_ACPI=n, the ID table left unused which is not what we want.
Instead of making linker to drop a section, drop ACPI_PTR().
As a side effect this makes driver ACPI and OF clean.

cancel_delayed_work_sync().
Since cancel_delayed_work(&chip->poweroff_work) does not guarantee that
tsl2563_poweroff_work() is not running, tsl2563_set_power(chip, 0) can be
called from tsl2563_poweroff_work() after tsl2563_get_power(chip) and
tsl2563_set_power(chip, 1) are called. Use _sync version in order to make
sure that tsl2563_poweroff_work() is no longer running.

cancel_delayed_work_sync().
Commit 9e61d901155bcd4e ("iio: light: tsl2563: Remove
flush_scheduled_work") replaced cancel_delayed_work() +
flush_scheduled_work() with cancel_delayed_work_sync() for only
tsl2563_probe() side.
Do the same thing for tsl2563_remove() side, which was added by
commit 388be4883952872b ("staging:iio: tsl2563 abi fixes and interrupt

As a part of patch series about wrong trigger register() and get()
calls order in the some IIO drivers trigger initialization path:
https://lore.kernel.org/all/20220524181150.9240-1-ddrokosov@sberdevices.ru/
runtime WARN_ONCE() is added to alarm IIO driver authors who make such
a mistake.
When an IIO driver allocates a new IIO trigger, it should register it
before calling the get() operation. In other words, each IIO driver
must abide by IIO trigger alloc()/register()/get() calls order.

It feels wrong and actually inconsistent to attach managed resources
to the IIO device object, which is child of the physical device object.
The rest of the ->probe() calls do that against physical device.

If CONFIG_PM_SLEEP is not defined using EXPORT_SIMPLE_DEV_PM_OPS()
in conjunction with pm_sleep_ptr() allows the compiler to remove
the unused code and data. This removes the need for __maybe_unused

Letting the compiler remove these functions when the kernel is built
without CONFIG_PM support is simpler and less error prone than the
use of #ifdef based config guards.
Removing instances of this approach from IIO also stops them being
copied into new drivers.
