Subject: [ALSA] ac97 - Allow drivers to set static volume resolution table
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7c5706bb33687ce82f30d9ac06dd1bdf71b2262e;p=mv-sheeva.git

[ALSA] ac97 - Allow drivers to set static volume resolution table

Modules: AC97 Codec

Add the pointer to a static volume resolution table to ac97 template,
so that the drivers can define the volume resolution, too.
