Hi Takashi, After merging the sound tree, today's linux-next build (x86_64 allmodconfig) failed like this: sound/usb/mixer.c: In function 'get_ctl_value_v1': sound/usb/mixer.c:308: error: 'struct usb_mixer_interface' has no member named 'ctrlif' Caused by commit 3d8d4dcfd423b01ef7ea7c3c97720764b7adb6df ("ALSA: usb-audio: simplify control interface access"). Grep is your friend ... I have used the sound tree from next-20100623 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/
