PATCH: Dell laptop lockup fix for ALSA

From: Alan Cox
Date: Mon Jun 21 2004 - 07:18:39 EST


OSS avoids the Dell lockup by not hitting the problem register (which
apparently breaks resume on a Sony laptop). ALSA keeps a flag and uses
pci subvendor info to clear it for problem Dell laptops. Unfortunately
there is at least one other Dell laptop which is affected. This adds
its sub id's

[Patch from Dan Williams @ Red Hat slightly reformatted by me]
