| |
2.6.33-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ben Hutchings <ben@decadent.org.uk>
commit e4146bb9088c01c8b6e82be11f0c371f8aff023c upstream.
As reported in <http://bugs.debian.org/552299>, MSI appears to be broken for this on-board device. We already have a quirk for the P5N32-SLI Premium; extend it to cover both variants of the board.
