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

------------------
From: Takashi Iwai <tiwai@suse.de>

patch 7583cb51a1e276591f57a2fae05489c878f8ef54 from mainline.

[ALSA] emu10k1 - Fix memory corruption

The number of mixer elements for SPDIF control don't match with the
actual array size (3).  This may result in a memory corruption that
overwrites the i2c_capture_source field (ALSA bug#3095).
