[PATCH 3.12 74/83] Input: twl4030-pwrbutton - ensure a wakeup event is recorded.

From: Jiri Slaby
Date: Mon Apr 27 2015 - 17:44:02 EST


From: NeilBrown <neilb@xxxxxxx>

3.12-stable review patch. If anyone has any objections, please let me know.

===============

commit c42bfd7f6cd26e8f712fc184460e32845d928d17 upstream.

This button is treated as a wakeup source, so we need to initialise it
correctly.

Without the device_init_wakeup() call, dev->power.wakeup will
be NULL, and pm_wakeup_event() will do nothing.
