From: Arnd Bergmann <[email protected]>
The error handling for platform_get_irq() failing no longer
works after a recent change, clang now points this out with
a warning:
drivers/gpu/host1x/dev.c:520:6: error: variable 'syncpt_irq' is uninitialized when used here [-Werror,-Wuninitialized]
if (syncpt_irq < 0)
^~~~~~~~~~
Fix this by removing the variable and checking the correct
error status.
Fixes: 625d4ffb438c ("gpu: host1x: Rewrite syncpoint interrupt handling")

Thanks Arnd, I saw some reports from kernelci about this, too.

Apologies if this has been reported already or has a solution in
progress but mainline is now broken because this change got separated
from the change it is fixing:
https://github.com/ClangBuiltLinux/continuous-integration2/actions/runs/4249931209/jobs/7391912774
https://storage.tuxsuite.com/public/clangbuiltlinux/continuous-integration2/builds/2M7y9HpiXB13qiC2mkHMyeZOcLW/build.log
I see this change sitting in the drm-tegra tree [1], which is getting
merged into -next, so it is fixed there, which is why we did not notice
any issues until the drm-next tree was merged into mainline. Can this be
fast tracked to Linus to unbreak clang builds with -Werror?

Generally first fallback should be drm-misc maintainers (or anyone else
with commit rights), but since this fell through cracks for weeks it seems
I'll pick it up to drm-fixes now directly.

Ok I think I found out why this fell through cracks, MAINTAINERS isn't
updated that host1x&tegra is maintained in drm-misc.
John, since Thierry is out, can you pls create the MAINTAINERS patch to
- point at drm-misc git repo everywhere needed
- add any missing host1x paths to the drm-misc entry so that
get_maintainers.pl adds the right people for this patch (currently it
doesn't)
Also should we have at least a 2nd person for tegra stuff (or well
maybe nvidia stuff in general) for drm-misc? Currently it's just
Thierry, and I don't think that's enough. Whomever gets volunteered
please follow
https://drm.pages.freedesktop.org/maintainer-tools/commit-access.html#drm-misc

Hm I thought you had a split where you feed -fixes through misc and
features through tegra.git? Just listing both trees would cover that.

Imo features still through tegra.git with just you is fine, there's
not going to be anyone else (like ci farms) blocked if that's held up
for a bit. It's more the bugfixes where a 2nd nvidia person would be
great.

We never actually moved host1x and Tegra DRM to drm-misc completely.
There's still a separate tree that feeds into linux-next. This made
sense a while ago because there was a lot going on, but development
speed has decreased recently, so we may want to fix that. The big
benefit is that drm-misc is better oiled than drm-tegra, so getting
things merged would be easier for everyone.
I'm all in favor of adding a second Tegra person to take pick up the
slack when necessary.
