X-Git-Tag: v6.13-rc1~122^2~23^2~40
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=017703370638c07cd6affe661118f697ee113881;p=thirdparty%2Fkernel%2Flinux.git

drm/bridge: imx8mp-hdmi-tx: Switch to SYSTEM_SLEEP_PM_OPS()

Replace SET_SYSTEM_SLEEP_PM_OPS with its modern SYSTEM_SLEEP_PM_OPS()
alternative.

The combined usage of pm_ptr() and SYSTEM_SLEEP_PM_OPS()
allows the compiler to evaluate if the runtime suspend/resume() functions
are used at build time or are simply dead code.

This allows removing the __maybe_unused notation from the runtime
suspend/resume() functions.
