Subject: ALSA: hda - Allow codec drivers to give own badness tables
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=98bd11152b5b8725b26d803dfdf205dc989d9832;p=openwrt%2Fstaging%2Fblogic.git

ALSA: hda - Allow codec drivers to give own badness tables

The standard badness values don't seem to fit to all preferences.
Some configuration prefer the side output over the headphone, some
want the speaker over the surround, etc.

This patch moves the badness table pointers into hda_gen_spec, so that
the codec driver can override them.
