Subject: [PATCH] usb: misc: uss720: remove redundant pointer usbdev

From: Colin Ian King <colin.king@...onical.com>

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

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