SubjectRe: [PATCH] net: usb: lan78xx: Fix suspend/resume PHY register access error
From: Cristian Birsan <>
Date: Thu, 12 Dec 2019 13:52:47 +0200

> Lan78xx driver accesses the PHY registers through MDIO bus over USB
> connection. When performing a suspend/resume, the PHY registers can be
> accessed before the USB connection is resumed. This will generate an
> error and will prevent the device to resume correctly.
> This patch adds the dependency between the MDIO bus and USB device to
> allow correct handling of suspend/resume.
> Fixes: ce85e13ad6ef ("lan78xx: Update to use phylib instead of mii_if_info.")
> Signed-off-by: Cristian Birsan <>
