Well, the kernel is in source form too. So I don�t see why can�t fix that
too.

No, the conversion is in two separate places; one to get something sensible
from the native format which doesn�t fit anything in the current V4L API. Or
do you suggest extending this API with every oddball format that comes
along? Please no...

*pfrt*. I already had to. And I�m sure I�m not the first to have a
�fix-in-kernel�.

It�s not a change, but an addition. I�m still somewhat ticked off by the
fact that the current drivers have such conversion routines, and nobody did
anything about it. And now suddenly this becomes THE issue to reject a
driver. It�s not fair. I�m not a paranoid person, but I am beginning to
wonder if this driver is being blocked for other reasons, like having a
binary only part (which is purely optional anyway).

If I do that now, hell will break loose. To me, this course of action is
perfectly acceptable for 2.5; but not while 2.4.* is slowly making its way
to more and more distributions and desktop machines. It would instantly
break all USB webcams.

I still maintain that this should have been fixed a long time ago then. It
would have saved me the disappointment of working 1.5 years on this, only to
be rejected because of some bad-ass policy nobody adhered to in the first
place.
