If CONFIG_PM_SLEEP is not set, make ARCH=x86_64 CROSS_COMPILE=x86_64-linux-gnu-, will be failed, like this:
sound/pci/hda/cs35l41_hda.c:583:12: error: ‘cs35l41_runtime_resume’ defined but not used [-Werror=unused-function] static int cs35l41_runtime_resume(struct device *dev) ^~~~~~~~~~~~~~~~~~~~~~ sound/pci/hda/cs35l41_hda.c:565:12: error: ‘cs35l41_runtime_suspend’ defined but not used [-Werror=unused-function] static int cs35l41_runtime_suspend(struct device *dev) ^~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make[3]: *** [sound/pci/hda/cs35l41_hda.o] Error 1
commit 1a3c7bb08826 ("PM: core: Add new *_PM_OPS macros, deprecate old ones"), add new marco RUNTIME_PM_OPS to fix this unused-function problem.
