Subject: ALSA: hda - Add workaround for MacBook Air 5,2 built-in mic
From: Takashi Iwai <[email protected]>
commit 2ddee91abe9cc34ddb6294ee14702b46ae07d460 upstream.
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.
