Subject: ALSA: hda - Add workaround for MacBook Air 5,2 built-in mic
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=2ddee91abe9cc34ddb6294ee14702b46ae07d460;p=openwrt%2Fstaging%2Fblogic.git

ALSA: hda - Add workaround for MacBook Air 5,2 built-in mic

MacBook Air 5,2 has the same problem as MacBook Pro 8,1 where the
built-in mic records only the right channel.  Apply the same
workaround as MBP8,1 to spread the mono channel via a Cirrus codec
vendor-specific COEF setup.
