Subject: [PATCH] net: ieee802154: 6lowpan: remove redundant pointers 'fq' and 'net'
Date: Tue, 31 Jul 2018 16:45:07 +0100	[thread overview]
Message-ID: <20180731154507.5247-1-colin.king@canonical.com> (raw)

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

Pointers fq and net are being assigned but are never used hence they
are redundant and can be removed.

Cleans up clang warnings:
warning: variable 'fq' set but not used [-Wunused-but-set-variable]
warning: variable 'net' set but not used [-Wunused-but-set-variable]
