[PATCH 19/20] usb/gadget/udc: renesas: Use pm_ptr() macro

From: Paul Cercueil
Date: Thu Sep 03 2020 - 07:52:23 EST


Use the newly introduced pm_ptr() macro, and mark the suspend/resume
functions __maybe_unused. These functions can then be moved outside the
CONFIG_PM_SUSPEND block, and the compiler can then process them and
detect build failures independently of the config. If unused, they will
simply be discarded by the compiler.
