Subject: [PATCH v2 net-next 08/10] net: atlantic: use intermediate variable to improve readability a bit

From: Nikita Danilov <ndanilov@...vell.com>

This patch syncs up hw_atl_a0.c with an out-of-tree driver, where an
intermediate variable was introduced in a couple of functions to
improve the code readability a bit.
