| |
2.6.32-stable review patch. If anyone has any objections, please let us know.
------------------
From: Daniel T Chen <crimsun@ubuntu.com>
commit 8f0f5ff6777104084b4b2e1ae079541c2a6ed6d9 upstream.
BugLink: https://launchpad.net/bugs/541802
The OR's hardware distorts at PCM 100% because it does not correspond to 0 dB. Fix this in patch_cxt5045() for all Packard Bell models.
