hwrng: imx-rngc - switch to DEFINE_SIMPLE_DEV_PM_OPS

[PATCH] hwrng: imx-rngc - switch to DEFINE_SIMPLE_DEV_PM_OPS

Posted by Martin Kaiser 1 year, 10 months ago

SIMPLE_DEV_PM_OPS is deprecated, replace it with DEFINE_SIMPLE_DEV_PM_OPS
and use pm_sleep_ptr for setting the driver's pm routines. We can now
remove the __maybe_unused qualifier in the suspend and resume functions.
