drivers/gpu/drm/bridge/adv7511/adv7511_drv.c appears to have been the
first one.  Looking at the logs it looks like it might've run out of
disk space transiently during the build, I've just rerun the test and it
seems to be OK so it looks like a false positive (and also gone and made
sure it has a lot more disk space to hopefully prevent that happening
again).

I did add back x86 allmodconfig relatively recently which pushed warning
counts up but that's the only thing unless I picked up a new x86
compiler from my distro.  However it's likely to have just been the
above if it was this specific build that you're noticing.
