[PATCH] spi: cadence: mark pm functions __maybe_unused
From: Arnd Bergmann
Date: Sat Apr 16 2016 - 16:39:53 EST
The newly added runtime PM support for the cadence spi driver
causes harmless warnings when PM is disabled:
drivers/spi/spi-cadence.c:681:12: warning: 'cnds_runtime_suspend' defined but not used
drivers/spi/spi-cadence.c:652:12: warning: 'cnds_runtime_resume' defined but not used
This adds __maybe_unused annotations to the respective functions
to shut up the warnings, while leaving the code in place for
compile testing and avoiding ugly #ifdefs.

Fixes: d36ccd9f7ea4 ("spi: cadence: Runtime pm adaptation")
