From 148b1eb93c9b54e61d7937b5a5760030276240ab Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sat, 16 Apr 2016 22:39:21 +0200 Subject: spi: cadence: mark pm functions __maybe_unused 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.
