Subject: libata: Early CFA adapters are not required to support mode setting
From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>
If we are doing a PIO setup for a CFA card and it blows up with a device error
then assume it is an older CFA card which doesn't support this rather than
failing the device out of existance.
Stands seperate to the quieting patch but that is obviously useful with this
change.
