I only needed a few patches to address all the warnings, so you don't need to split up the patch for this purpose, though it may be easier to get it merged anyway. I see now that Linus has already applied the same fix as part of https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9d82973e032e2 It's just not yet in today's linux-next, but my patch is now obsolete. Linus, let me know if you would like me to Cc you on the other gcc-10 warning fixes I have and possibly apply some directly. I have patches for all gcc-10 and clang-10 warnings now, and am in the process of getting them out to the subsystem maintainers. Arnd
