How do you mean? I was careful to check what sparse was referring to,
then investigate how memset should be used with pointers with a
__iomem qualifier. I'd like to be able to improve my patch
descriptions going forward as best I can :)

Unfortunately not, I am trying to keep these changes as simple code
fixes that ought not to affect actual hardware behaviour as I can
(though of course you can never be entirely sure that's the case!)

I suspect that Sudip must have some real hardware, is this the case
Sudip? If it isn't too presumptuous of me to ask, perhaps you might be
able to check patches that are successfully merged into
staging-testing?

Best,
