Subject: net: smc91x: take into account register shift
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=876a55b8e255702d2c406872fd791817a3c98bd1;p=linux-beck.git

net: smc91x: take into account register shift

This aligns smc91x with its cousin, namely smc911x.c.
This also allows the driver to run also in a device-tree based lubbock
board build, on which it was tested.
