Subject: [PATCH] drm/panel: Convert to DEFINE_SIMPLE_DEV_PM_OPS()
Date: Thu, 20 Aug 2026 16:01:19 +0700 [thread overview]
Message-ID: <20260820090119.2107869-1-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, and reduces kernel size in case CONFIG_PM or
CONFIG_PM_SLEEP is disabled.
