From: Matt Flax <flatmax@xxxxxxxxxxx>
The cs4265 driver declares the "MMTLR Data Switch" register setting with
a 0 register value rather then the 0x12 register (CS4265_SPDIF_CTL2).
This incorrect value causes alsamixer to fault with the output :
cannot load mixer controls: Input/output error
This patch corrects the register value. alsamixer now runs.
