Subject: [PATCH v2] input: don't call input_dev_release_keys() in resume

From: Aleksej Makarov <aleksej.makarov@...ymobile.com>

When waking up the platform by pressing a specific key, sending a
release on that key makes it impossible to react on the event in
user-space. This is fixed by moving the input_reset_device() call to
resume instead.
