ALSA: hda: Fix max PCM level to 0 dB for Fujitsu-Siemens laptops using CX20549 (Venice)
commit 0b587fc4d35afb1bc0fc3d890084bb14c78372dc upstream. BugLink: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4792 Cristian reported that these models have really bad sound above 6 dB and proposed the original patch. I've updated the comment to reflect this change.
