[alsa-devel] [PATCH 8/9] ALSA: usb-audio: remove redundant pointer 'urb'

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Pointer 'urb' is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'urb' set but not used [-Wunused-but-set-variable]
