When CONFIG_PM is disabled, we get a warning about the clock handling being unused: drivers/mmc/host/tmio_mmc_core.c:937:13: error: 'tmio_mmc_clk_disable' defined but not used [-Werror=unused-function] static void tmio_mmc_clk_disable(struct tmio_mmc_host *host) ^~~~~~~~~~~~~~~~~~~~ drivers/mmc/host/tmio_mmc_core.c:929:12: error: 'tmio_mmc_clk_enable' defined but not used [-Werror=unused-function] static int tmio_mmc_clk_enable(struct tmio_mmc_host *host) ^~~~~~~~~~~~~~~~~~~ As the clock handling is now done elsewhere, this is only used when power management is enabled. We could make the functions as __maybe_unused, but since there is already an #ifdef section, it seems easier to move the helpers closer to their callers.
