| |
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]
