3.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Takashi Iwai <redacted> 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.
