just for the record: I don't like this patch because I think it's highly
at91 specific and could so well live in that driver. Moreover I'm not
conviced yet that it's really the correct thing to do even for this
driver. So please don't apply, at least until we're done with the
discussion of patch 2.

Best regards
Uwe
