Subject: [PATCH] ALSA: hda - MacBookPro 5,3 line-in support

commit 4e7d7c6018567fa03f387d06602d4145c75ebbe0 upstream.

I've found the following patch is necessary to enable line-in on
my MacBookPro 5,3 machine.  With the patch applied I've successfully
recorded audio from the line-in jack.  This is based on the existing
5,5 support.
