Subject: [PATCH] rtc: sh: Convert to DEFINE_SIMPLE_DEV_PM_OPS()
Date: Wed,  9 Jul 2025 20:47:52 +0200	[thread overview]
Message-ID: <396d4a769b8d3c6fec43c65022cdfd8a6854524a.1752086758.git.geert+renesas@glider.be> (raw)

Convert the Renesas SuperH On-Chip RTC driver from 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.
