====================
ks8851 fixes & cleanups

Four fixes and two cleanups for the Microchip (formerly Micrel) KSZ8851
SPI Ethernet driver.

Some of the fixes might even pass as stable material, but I haven't marked
them as such for cautiousness: Doesn't hurt letting them bake in linux-next
for a few weeks to raise the confidence, even though we've tested them
extensively on our Revolution Pi open source PLCs.
