[089/272] ALSA: hda - Fix multi-headphone handling for Realtek codecs

From: Greg KH
Date: Tue Feb 15 2011 - 20:37:53 EST


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

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

From: Takashi Iwai <tiwai@xxxxxxx>

commit b2d0576055bd1cafcd91a23cf85064815f1396cd upstream.

When multiple headphone pins are defined without line-out pins, the
driver takes them as primary outputs. But it forgot to set line_out_type
to HP by assuming there is some rest of HP pins. This results in some
mis-handling of these pins for Realtek codec parser. It takes as if
these are pure line-out jacks.
