Subject: [PATCH] net: hns3: remove redundant variable 'protocol'
Date: Wed,  4 Jul 2018 08:59:25 +0100	[thread overview]
Message-ID: <20180704075925.16163-1-colin.king@canonical.com> (raw)

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

Variable 'protocol' is being assigned but is never used hence it is
redundant and can be removed.

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