[PATCH v2] pinctrl: imx: Switch to LATE_SYSTEM_SLEEP_PM_OPS()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Fabio Estevam <festevam@xxxxxxx>

Replace SET_LATE_SYSTEM_SLEEP_PM_OPS() with its modern
LATE_SYSTEM_SLEEP_PM_OPS() alternative.

The combined usage of pm_ptr() and LATE_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.

Signed-off-by: Fabio Estevam <festevam@xxxxxxx>

Changes since v1:
- Pass pm_ptr() to the correct ops structure.
