SubjectRe: [PATCH 20/28] net: bcm63xx: avoid referencing uninitialized variable
From: Arnd Bergmann <>
Date: Tue, 18 Oct 2016 00:16:08 +0200

> gcc found a reference to an uninitialized variable in the error handling
> of bcm_enet_open, introduced by a recent cleanup:
> drivers/net/ethernet/broadcom/bcm63xx_enet.c: In function 'bcm_enet_open'
> drivers/net/ethernet/broadcom/bcm63xx_enet.c:1129:2: warning: 'phydev' may be used uninitialized in this function [-Wmaybe-uninitialized]
> This makes the use of that variable conditional, so we only reference it
> here after it has been used before. Unlike my normal patches, I have not
> build-tested this one, as I don't currently have mips test in my
> randconfig setup.
> Fixes: 625eb8667d6f ("net: ethernet: broadcom: bcm63xx: use phydev from struct net_device")
