I objected to this last patch when it was posted on the list.  The sysfs
file should just not be present if the functionality is not there, no
need to add the "-EINVAL" logic to it instead.

Having a sysfs file that says it can be read, and then rejecting that
read with an error is NOT ok.

I'll cherry-pick the other two patches, but this one needs to be
reworked.
