If CONFIG_PM is not set.
make ARCH=x86_64 CROSS_COMPILE=x86_64-linux-gnu-, will be failed, like this:
drivers/mmc/host/sdhci-pci-gli.c:834:13: error: ‘gl9763e_set_low_power_negotiation’ defined but not used [-Werror=unused-function]
static void gl9763e_set_low_power_negotiation(struct sdhci_pci_slot *slot, bool enable)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
make[3]: *** [drivers/mmc/host/sdhci-pci-gli.o] Error 1
To fix building warning, wrap all related code with CONFIG_PM.
