Audio DSP drivers on KVM host and guest.

I am fine with this patch but won't add an RB because of the (many) checkpatch
errors.  Based on the comment I made on the previous set seeing those was
unexpected.

Thanks,
Mathieu

Are you using "--strict?" Sorry, I don't see any checkpatch errors, only warnings. 
Most of them are "over 80 characters" which as we now know is no more an issue, 
I just haven't updated my tree yet. Most others are really minor IMHO. Maybe one 
of them I actually would want to fix - using "help" instead of "---help---" in 
Kconfig. What errors are you seeing in your checks?

Thanks

No, plane checkpatch on the rproc-next branch.

There is a thread discussing the matter but I have not seen a clear resolution
yet.

Minor or not, if checkpatch complains then it is important enough to address.  I
am willing to overlook the lines over 80 characters but everything else needs to
be dealt with.

Mathieu

I think the resolution is pretty clear as defined by Linus, but maybe it has changed 
again since I last checked.

Sure, checkpatch should be run before each patch submission and whatever it reports 
should be considered. As Documentation/process/submitting-patches.rst clearly 
states:

"Check your patches with the patch style checker prior to submission
(scripts/checkpatch.pl).  Note, though, that the style checker should be
viewed as a guide, not as a replacement for human judgment.  If your code
looks better with a violation then its probably best left alone."

So, yes, I checked all what checkepatch reported and used my judgement to decide 
which recommendations to take and which to ignore.

I will let Michael and friends decide how to handle checkpatch warnings in the
vhost subsystem but as far as remoteproc/rpmsg are concerned, I will not review
patches that trigger warnings.

There is a patch in linux-next that deprecates warnings for lines over 80
characters, so those are no longer a problem.
