[PATCH] media: tw68: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

[PATCH] media: tw68: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

[Triet Hoang]

Convert the deprecated SIMPLE_DEV_PM_OPS
to DEFINE_SIMPLE_DEV_PM_OPS
and pm_sleep_ptr().

This lets us drop the __maybe_unused annotations
from its suspend and resume callbacks,
also reduces kernel size in case CONFIG_PM or
CONFIG_PM_SLEEP is disabled.
