Subject[PATCH 2/2] media: rc: gpio-ir-recv: Fix support for wake-up
Date
The driver was intended from the start to be a wake-up source for the
system, however due to the absence of a suitable call to
device_set_wakeup_capable(), the device_may_wakeup() call used to decide
whether to enable the GPIO interrupt as a wake-up source would never
happen. Lookup the DT standard "wakeup-source" property and call
device_init_wakeup() to ensure the device is flagged as being wakeup
capable.

Fixes: fd0f6851eb46 ("[media] rc: Add support for GPIO based IR Receiver driver")
