From 69898e512a4c27017aec43796bef8fe1dd1ec661 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Sun, 22 Jan 2012 23:27:54 -0800 Subject: [PATCH] Input: samsung-keypad - don't synchronise with runtime PM put We don't actually care if the device has been runtime suspended immediately so we can just drop the reference without waiting for any state change to be implemented. This may allow us to avoid some suspend/resume cycles and is a bit more friendly to the rest of the system.
