From: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>
[ Upstream commit a6f06b909fee72c679c565adfa7f080f9595e336 ]
The conversion to DEFINE_NOIRQ_DEV_PM_OPS() lost the ability of the
compiler to optimize away the struct dev_pm_ops object when it is not
needed.
Fix this by replacing the use of pm_sleep_ptr() by a custom wrapper.
Fixes: 727eb02eb753375e ("pinctrl: renesas: Switch to use DEFINE_NOIRQ_DEV_PM_OPS() helper")
