Subject: [PATCH 3.12 014/123] ALSA: hda_intel: apply the Seperate stream_tag for Sunrise Point

From: Libin Yang <libin.yang@...el.com>

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

===============

commit db48abf4367cb1f9e118defee0a37238638c2752 upstream.

The total stream number of Sunrise Point's input and output stream
exceeds 15, which will cause some streams do not work because
of the overflow on SDxCTL.STRM field if using the legacy
stream tag allocation method.

This patch uses the new stream tag allocation method by add
the flag AZX_DCAPS_SEPARATE_STREAM_TAG for Skylake platform.
