Subject: [PATCH] net: hso: remove redundant unused variable dev
Date: Tue, 31 Oct 2017 12:01:47 +0000 [thread overview]
Message-ID: <20171031120147.22348-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.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
Signed-off-by: Colin Ian King <colin.king@canonical.com>
