Subject: [patch 05/29] ALSA: HDA: Realtek: Fixup jack detection to input subsystem

2.6.37-stable review patch.  If anyone has any objections, please let us know.

------------------

From: David Henningsson <david.henningsson@...onical.com>

commit f0ce27996217d06207c8bfda1b1bbec2fbab48c6 upstream.

This patch fixes an error in the jack detection reporting,
causing the jack detection sometimes not to be reported
correctly to the input subsystem. It should apply to several
Realtek codecs.
