Subject: ALSA: usb: Remove obsoleted fields from struct snd_usb_substream
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=22026c1a7be900cc6dabd6be37a77bb217d2d837;p=~shefty%2Frdma-dev.git

ALSA: usb: Remove obsoleted fields from struct snd_usb_substream

Many fields have been moved to struct snd_usb_endpoint.
Also fix the proc output to correspond to the new structure.
