Subject: ACPI: PM: Print debug messages when enabling GPEs for wakeup
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fbc9418f099d457b91bf14aef8c4bfc498bb2437;p=linux.git

ACPI: PM: Print debug messages when enabling GPEs for wakeup

In sufficiently complicated GPE configurations it is hard to
determine which GPE could be the source of system wakeup from a sleep
state, so make __acpi_device_wakeup_enable() print that information
to the kernel log if debugging is enabled.
