Miller" <davem@...emloft.net>, netdev@...r.kernel.org Cc: kernel-janitors@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH][V2] net: ethernet: sun: remove redundant variables adv and lpa and mii_reads From: Colin Ian King <colin.king@...onical.com> Variables adv and lpa are being assigned but are never used hence they are redundant and can be removed. Also remove the unncessary mii_reads too.
