But the volume quirks for certain devices are applied only in mixer_ctl_feature_info() thus only at the very first probe and will be missing when the volume range is initialized later. This patch moves the volume quirk code to be always called from the volume-range extraction (get_min_max()), so that the quirks are properly applied in the later init time.

One problem was that the first implementation was wrong -- the bit after the shift must be checked. However, this would still give many regressions on machines with broken BIOS. They set this bit wrongly even on active pins. A workaround is to check whether all pins contain this bit. As far as I've checked, broken BIOSen set this bit on all pins, no matter whether active or not. In such a case, the driver should ignore this bit check.
