[alsa-devel] [RESEND PATCH] ASoC: OMAP: HDMI: Initialize IEC-60958 channel status word

[Ricardo Neri]

As the IEC-60958 channel status word is set by ANDing and ORing with
the appropriate definitions, the word bytes need to be initialized
to zero to avoid misconfiguration due to previous hw_params calls.
