Subject: [PATCH] net: bcmgenet: fix MoCA LED control
References: bsc#1012628
Patch-mainline: 6.2.3
Git-commit: a7515af9fb8f0890fe540b108def4a86b9e8330a

[ Upstream commit a7515af9fb8f0890fe540b108def4a86b9e8330a ]

When the bcmgenet_mii_config() code was refactored it was missed
that the LED control for the MoCA interface got overwritten by
the port_ctrl value. Its previous programming is restored here.

Fixes: 4f8d81b77e66 ("net: bcmgenet: Refactor register access in bcmgenet_mii_config")
