Merge an immutable branch between MFD, GPIO, Input and PWM to resolve
conflicts for the merge window pull request.

evdev has switched to match on EV_SYN instead of relying on non-zero
driver_info field to allow matching to all devices. Remove special
handling from input core.

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree
over and remove the historical wrapper inlines.

Conversion was done with coccinelle plus manual fixups where necessary.

Switch input core to use "guard" notation when acquiring spinlocks and
mutexes to simplify the code and ensure that locks are automatically
released when control leaves critical section.

Pull input updates from Dmitry Torokhov:

 - support for NT36672A touchscreen added to novatek-nvt-ts driver

 - a change to ads7846 driver to prevent XPT2046 from locking up

 - a change switching platform input dirves back to using remove()
   method (from remove_new())

 - updates to a number of input drivers to use the new cleanup
   facilities (__free(...), guard(), and scoped-guard()) which ensure
   that the resources and locks are released properly and automatically

 - other assorted driver cleanups and fixes.

Prepare input updates for 6.13 merge window.

Sometimes it is useful to observe (and maybe modify) data coming from
an input device, but only do that if there are other users of such input
device. An example is touchpad switching functionality on Lenovo IdeaPad
Z570 where it is desirable to suppress events coming from the touchpad
if user toggles touchpad on/off button (on this laptop the firmware does
not stop the device).

Introduce notion of passive observers for input handlers to solve this
issue. An input handler marked as passive observer behaves exactly like
any other input handler or filter, but with one exception: it does not
open/start underlying input device when attaching to it.

Pull input fixes from Dmitry Torokhov:

 - a fix for regression in input core introduced in 6.11 preventing
   re-registering input handlers

 - a fix for adp5588-keys driver tyring to disable interrupt 0 at
   suspend when devices is used without interrupt

 - a fix for edt-ft5x06 to stop leaking regmap structure when probing
   fails and to make sure it is not released too early on removal.

  Input: fix regression when re-registering input handlers
  Input: adp5588-keys - do not try to disable interrupt 0
  Input: edt-ft5x06 - fix regmap leak when probe fails

Commit d469647bafd9 ("Input: simplify event handling logic") introduced
code that would set handler->events() method to either
input_handler_events_filter() or input_handler_events_default() or
input_handler_events_null(), depending on the kind of input handler
(a filter or a regular one) we are dealing with. Unfortunately this
breaks cases when we try to re-register the same filter (as is the case
with sysrq handler): after initial registration the handler will have 2
event handling methods defined, and will run afoul of the check in
input_handler_check_methods():

	input: input_handler_check_methods: only one event processing method can be defined (sysrq)
	sysrq: Failed to register input handler, error -22

Fix this by adding handle_events() method to input_handle structure and
setting it up when registering a new input handle according to event
handling methods defined in associated input_handler structure, thus
avoiding modifying the input_handler structure.
