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. Fixes: d36ccd9f7ea4 ("spi: cadence: Runtime pm adaptation") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Shubhrajyoti Datta <shubhraj@xilinx.com> Signed-off-by: Mark Brown <broonie@kernel.org>
