The structure returned from the function wakeup_source_register() is not
currently checked to see that a valid structure is returned. If
wakeup_source_register fails to register the wake-up source, then this
function will return a NULL pointer and this will lead to a crash when
defereferencing this pointer. Therefore, check that a valid structure is
returned from wakeup_source_register() and if not then return an error
from the probe function.

The function devm_gpiod_get_optional() will return an error code encoded
as a pointer type if the GPIO requested is not found. Therefore, we need
to use the IS_ERR() macro to determine if the GPIO is valid, otherwise
we could incorrectly attempt to dereference an invalid pointer. This bug
was introduced when migrating the bluedroid driver to use the gpiod
functions.

There are 2 timer defined. One statically and one in the
bluedroid_pm_data struct. Both timers call the same function on expiration. In the case of the statically defined timer this is a problem because it assumes that the timer is part of the bluedroid_pm_data and so calling timer_container_of() or from_timer() results in an invalid pointer and hence kernel panic. Fix this by
removing the statically defined timer.

In Linux v6.16, commit 41cb08555c41 ("treewide, timers: Rename
from_timer() to timer_container_of()") renamed 'from_timer()' to
'timer_container_of()'. Given that this is a macro we can simplfy see if
the macro 'timer_container_of' is defined and if so use this otherwise
fall back to 'from_timer()'. Update the necessary drivers to fix the
build for Linux v6.16.

In Linux v6.15, the timer APIs hrtimer_init() and del_timer() have been
removed. The hrtimer_setup() was added in Linux v6.13 to replace
hrtimer_init() and hrtimer_init() have finally been removed. The
functions del_timer()/del_timer_sync() were renamed to
timer_delete()/timer_delete_sync() in Linux v6.15. Use conftest to
detect these changes and update the drivers as necessary.

The build of driver is disabled from Linux 6.2 due to
changes in core kernel where API of_get_named_gpio_flags()
has been removed.
This APIS is removed in commit 40fc56ee608cdb ("gpiolib:
of: remove of_get_gpio[_flags]() and of_get_named_gpio_flags()")
in Linux 6.2.
Add support to use the new APIs for Linux 6.2 onwards.

Upstream commit "7d0b80647f73"
[gpiolib: remove unused gpio_cansleep()]
Removed gpio_cansleep() API as there are no upstream users.
Replace the usage of gpio_cansleep() with gpiod_cansleep(). This is also
backwards compatible with older Kernels.
