My plan was to fix them all, then move each warning to W=0. Arnd recently submitted a set doing just that for a bunch of them. https://lore.kernel.org/all/20230811140327.3754597-1-arnd@xxxxxxxxxx/ I like to think a bunch of this is built on top of my previous efforts. GPU is a particularly tricky though - the warnings seem to come in faster than I can squash them.

That would we awesome! We'd just need buy-in. -- Lee Jones [李琼斯]
