[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). Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
