Subject: [ 071/104] ALSA: hda - Fix typo in checking IEC958 emphasis bit

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

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

From: Takashi Iwai <tiwai@...e.de>

commit a686fd141e20244ad75f80ad54706da07d7bb90a upstream.

There is a typo in convert_to_spdif_status() about checking the
emphasis IEC958 status bit.  It should check the given value instead
of the resultant value.
