Note:  Magnus' address seems to be wrong.  I don't know a working one.

I wonder that you don't have this impression with "uio_pdrv".

I thought the driver in discussion is kind of a standard way to create a
platform driver using uio.
(At least you called it "generic UIO platform device driver" above :-)

I tried to point out that uio_pdrv_genirq is (probably) the only
platform driver that has _pdrv in its name.
