Subject: [PATCH 3.16 169/306] ALSA: usb-audio: Add quirk for Syntek STK1160

3.16.40-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Marcel Hasler <mahasler@...il.com>

commit bdc3478f90cd4d2928197f36629d5cf93b64dbe9 upstream.

The stk1160 chip needs QUIRK_AUDIO_ALIGN_TRANSFER. This patch resolves
the issue reported on the mailing list
(http://marc.info/?l=linux-sound&m=139223599126215&w=2) and also fixes
bug 180071 (https://bugzilla.kernel.org/show_bug.cgi?id=180071).
