Subject: usb: dwc3: of-simple: mark PM functions as __maybe_unused
Date: Tue, 31 Jul 2018 23:24:05 +0200 [thread overview]
Message-ID: <20180731212405.27572-1-anders.roxell@linaro.org> (raw)
The suspend/resume functions are not referenced when power messagement
is enabled:
CC drivers/video/fbdev/matrox/matroxfb_DAC1064.o
drivers/usb/dwc3/dwc3-of-simple.c:223:12: warning: ‘dwc3_of_simple_resume’ defined but not used [-Wunused-function]
static int dwc3_of_simple_resume(struct device *dev)
^~~~~~~~~~~~~~~~~~~~~
drivers/usb/dwc3/dwc3-of-simple.c:213:12: warning: ‘dwc3_of_simple_suspend’ defined but not used [-Wunused-function]
static int dwc3_of_simple_suspend(struct device *dev)
^~~~~~~~~~~~~~~~~~~~~~
This marks them as __maybe_unused to let the compiler drop the function
without complaining.
Fixes: 76251db86561 ("usb: dwc3: of-simple: reset host controller at suspend/resume")
