Subject: [PATCH 3.13 012/259] ALSA: hda/hdmi - apply all Haswell fix-ups to Broadwell display codec

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

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

From: Mengdong Lin <mengdong.lin@...el.com>

commit 75dcbe4dc251ebc28cdf0797b85774cdf53a4d29 upstream.

Broadwell and Haswell have the same behavior on display audio. So this patch
defines is_haswell_plus() to include codecs for both Haswell and its successor
Broadwell, and apply all Haswell fix-ups to Broadwell.
