[PATCH net] net: phy: bcm84881: Fix some error handling paths
From: Christophe JAILLET <hidden>
Date: 2024-10-03 19:04:44
Also in:
kernel-janitors, lkml
Subsystem:
broadcom ethernet phy drivers, ethernet phy library, networking drivers, the rest · Maintainers:
Florian Fainelli, Andrew Lunn, Heiner Kallweit, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds
If phy_read_mmd() fails, the error code stored in 'bmsr' should be returned
instead of 'val' which is likely to be 0.
Fixes: 75f4d8d10e01 ("net: phy: add Broadcom BCM84881 PHY driver")
