Subject[PATCH 3/6] drivers/acpi: fix button driver compile error when CONFIG_PM_SLEEP is undefined
Date
button driver defines acpi_button_resume() when CONFIG_PM_SLEEP is defined.
This results in the following compile error when CONFIG_PM_SLEEP is undefined.

drivers/acpi/button.c:85:8: error: ‘acpi_button_resume’ undeclared here (not in a function)
