3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <ti...@suse.de>
commit 2ca320e294a738c9134a71b5029de05edbfc7aad upstream.
Without the dynamic minor assignment, HDMI codec may have less PCM
instances than the number of pins, which eventually leads to Oops.
