Subject: [PATCH v1 net] lan743x: Remove phy_read from link status change function
Date: Mon, 7 Jan 2019 14:00:09 -0500	[thread overview]
Message-ID: <1546887609-16152-1-git-send-email-Bryan.Whitehead@microchip.com> (raw)

It has been noticed that some phys do not have the registers
required by the previous implementation.

To fix this, instead of using phy_read, the required information
is extracted from the phy_device structure.

fixes: 23f0703c125b ("lan743x: Add main source files for new lan743x driver")
