Subject: [PATCH] mtd: rawnand: stm32_fmc2: Convert to DEFINE_SIMPLE_DEV_PM_OPS()
Date: Sat, 22 Aug 2026 04:59:56 +0000	[thread overview]
Message-ID: <20260822045957.12511-1-triet.hoang.dev@gmail.com> (raw)

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.
