How many warnings showed up when you applied this patch? I got zero for x86_64 and arm64 defconfig builds of linux-next with this applied.

I view __must_check as a good thing, and encourage its application, unless someone can show that a certain function would be useful to call without it. -- Thanks, ~Nick Desaulniers
