> Subject: [PATCH 3/5] media: renesas: fdp1: Convert to RUNTIME_PM_OPS()
>
> Convert the Renesas Fine Display Processor driver from
> SET_RUNTIME_PM_OPS() to RUNTIME_PM_OPS() and pm_ptr(). This lets us
> drop the __maybe_unused annotations from its runtime suspend and resume
> callbacks, and reduces kernel size in case CONFIG_PM is disabled.
