Subject: ALSA: vx: hard dependency on the standard fw loader
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0d144de9af28f23d28e4cdf28a08e25e9ad3b41c;p=openwrt%2Fstaging%2Fblogic.git

ALSA: vx: hard dependency on the standard fw loader

Yet again like previous two commits, drop the old hwdep user-space
firmware code from vx driver (snd-vxpocket and snd-vx222).
