[PATCH] net: alx: remove redundant variable old_duplex

From: Colin King
Date: Wed Jul 04 2018 - 03:15:39 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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

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