[PATCH v1] nubus: Remove redunant driver match function

[PATCH v1] nubus: Remove redunant driver match function

[Lizhe]

If there is no driver match function, the driver core assumes that each
candidate pair (driver, device)matches, see driver_match_device()

As it happens, the same patch from a different author was accepted last 
week.

You sent a patch doing this conversion to several drivers at once[1]
back in May 2022. You were asked to split up by subsystem and I cannot
find anything more recent; neither in my inbox nor on
lore.kernel.org[2]. So unless I missed something I wouldn't claim you
already sent this patch.

Even if I'd agree, I couldn't. That's up to Finn (I think) to drop this
patch again from his queue and then accept a similar patch from you. If
that's what Finn want's to do and it makes you happy, I won't oppose for
the sake of resolving that argument.

Having said that I didn't even remember your patch. I just stumbled over
this patch opportunity while doing some treewide cleanups.

Best regards
Uwe

I leave it up to Geert to apply Nubus patches that pass review. There is 
no git tree for this subsystem and the only arch to make use of it so far 
is m68k.

In my opinion, there's nothing novel about deleting code so it's quite 
meaningless what "git log" says about authorship. That's doubly true for 
redundant code, which compilers elide as a matter of course.

If some developers are receiving incentives to do juanitorial work (like 
running coccinelle scripts) then I'd like to know whether a line added has 
the same price as a line deleted.

Maybe some developers are deleting redundant code I wrote so as to make my 
life easier as the maintainer. Maybe they are not getting paid for that. 
I'm not aware of that having happened here, but if it did, thanks a lot.

Iff the patch under discussion is considered for applying: I just
noticed we want:

	$Subject ~= s/redunant/redundant/

What can I possibly do? Your link shows a thread with an acked-by from me 
from 10 months ago. Also in that thread is a review from Greg 
Kroah-Hartman that you also appear to have missed.
