Well, if I sign-off on a patch, I want to know about gcc warnings that
were added by it, don't not email me just because you think I'm busy.

I don't think you should drop the committer, but maybe that's just me.

This might get tougher in some areas of the kernel like the
drivers/staging/ tree where people incrementally fix things up, like fix
trailing space issues on one patch, which doesn't change the rest of the
line that might have had coding style or sparse issues in it.  That's
why I can't always run checkpatch.pl on patches sent to me, and why
sparse might not help out.

But, I'd love to see sparse run on other areas of the kernel (i.e.
anything not in drivers/staging/) hopefully it would get those areas
fixed up properly.

thanks,
