Hi Takashi, After merging the sound tree, today's linux-next build (x86_64 allmodconfig) failed like this: In file included from drivers/usb/gadget/audio.c:37: drivers/usb/gadget/f_audio.c:104: error: 'UAC_MUTE_CONTROL' undeclared here (not in a function) drivers/usb/gadget/f_audio.c:113: error: 'UAC_VOLUME_CONTROL' undeclared here (not in a function) Presumably caused by commit 65f25da44b51f55e3a74301c25f29263be2bf1ba ("ALSA: usb-audio: unify constants from specification"). I have used the version of the sound tree from next-20100531 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/
