Subject: [ALSA] hda-intel - Add probe_mask blacklist
X-Git-Tag: v2.6.24-rc1~832^2~156
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=669ba27a6e25251427bde8f4980f62733a8f0c7e;p=linux-2.6-omap-h63xx.git

[ALSA] hda-intel - Add probe_mask blacklist

Added the black-list of probe_mask option to set the default value for
known non-working devices.  Currently, Thinkpad *60 and *61 series are set.
I'm afraid more will be added to the list in near future...
