[PATCH 4.17 181/324] net: phy: marvell: change default m88e1510 LED configuration

From: Greg Kroah-Hartman
Date: Thu Aug 23 2018 - 04:53:27 EST


4.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Wang Dongsheng <dongsheng.wang@xxxxxxxxxxxxxxxx>

[ Upstream commit 077772468ec141b22e1e7c0c58bc09e2f9dc8762 ]

The m88e1121 LED default configuration does not apply m88e151x.
So add a function to relpace m88e1121 LED configuration.
