Patch from Steven Scholz:
should we rename the define into CONFIG_FEATURE_HDPARM_HDIO_DMA and
use it for "set" and "get" ???
Since although CONFIG_FEATURE_HDPARM_HDIO_GET_DMA is _not_ set I still
can use "hdparm -d 1 /dev/hda" to switch the DMA on.
Is this desireable or meant to be like that?
So how about the applied patch?
