Subject: OLPC: ALSA: fix cs5535audio's MIC GPIO to enable input
From: Andres Salomon <dilinger@xxxxxxxxxxxxxxx>
Previously the MIC GPIO was set to output mode, and when checking the
status after setting it we were checking OUTPUT_VAL. This worked, though
I'm not quite sure why. Instead, if we actually check the READ_BACK
value, it doesn't work unless the GPIO is in bidirectional mode. Thus,
enable input mode as well.
