From 62a3106697f3c6f9af64a2cd0f9ff58552010dc8 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Wed, 22 Dec 2021 00:39:37 +0000 Subject: [PATCH] net: broadcom: bcm4908enet: remove redundant variable bytes The variable bytes is being used to summate slot lengths, however the value is never used afterwards. The summation is redundant so remove variable bytes.
