Subject: [PATCH 1/6] drivers/acpi: fix ac driver compile error when CONFIG_PM_SLEEP is undefined

ac driver defines acpi_ac_resume() when CONFIG_PM_SLEEP is defined. This
results in the following compile error when CONFIG_PM_SLEEP is undefined.

drivers/acpi/ac.c:248:8: error: ‘acpi_ac_resume’ undeclared here (not in a function)
