Without CONFIG_PM, we get a new build warning here:
drivers/usb/renesas_usbhs/common.c:860:12: error: 'usbhsc_resume' defined but
not used [-Werror=unused-function]
static int usbhsc_resume(struct device *dev)
^~~~~~~~~~~~~
drivers/usb/renesas_usbhs/common.c:844:12: error: 'usbhsc_suspend' defined but
not used [-Werror=unused-function]
static int usbhsc_suspend(struct device *dev)
^~~~~~~~~~~~~~
No idea why this never happened before, but it's trivial to work
around by marking the functions as __maybe_unused so the compiler
can silently discard them.
