X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1f14a657d87aa0e1a6c08c2e31588fbca34a8844;p=openwrt%2Fstaging%2Fblogic.git

[ALSA] usb-audio: fix Edirol UA-20 support

Modules: USB generic driver

Somebody at Edirol fucked up and released a new revision of the UA-20
without class-specific descriptors, so now we have to hard-code the
sample format.
