The mmc pm notifiers were recently reworked, but the new code produces a lot of warnings when CONFIG_PM_SLEEP is disabled: In file included from ../drivers/mmc/core/sdio_bus.c:27:0: drivers/mmc/core/core.h:97:13: warning: 'mmc_register_pm_notifier' defined but not used [-Wunused-function] The obvious solution is to add the 'inline' keyword at the function definition, as it should be for any function defined in a header file.
