Subject: [PATCH] net: hso: remove redundant unused variable dev

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

The pointer dev is being assigned but is never used, hence it is
redundant and can be removed. Cleans up clang warning:

drivers/net/usb/hso.c:2280:2: warning: Value stored to 'dev' is
never read
