Subject: [PATCH] UIO: Change driver name of uio_pdrv

Hi Greg,
I'm just about to use the generic UIO platform device driver in a
project. I noticed the driver registers itself simply as "uio". We
should choose a more unique name here. The oneliner below goes on top of
the other UIO patches you've got in your queue right now. This is not in
mainline yet.

Thanks,
Hans

-------------------------

The generic UIO platform device driver should be given a unique driver ID and
not just "uio". This is especially important since Magnus Damm announced a
similar driver named uio_pdrv_genirq. We should get the names right before
this hits mainline.

I don't care much, but IMHO "uio" is fine, because the name has a
context (i.e. it's the name of a platform device) and so adding "_pdrv"
doesn't yield a more clear result.

I don't claim to know all or even many platform drivers, the ones I
currently use (and that are in mainline, too) are:

gpio-keys
i2c-gpio
leds-gpio
physmap-flash
serial8250

and for all of these I consider it right not to have a "pdrv" suffix.

So using uio_genirq here would be the logical consequence.

But as I said, I don't care much and both options are fine for me.

Best regards
Uwe
