Subject: [PATCH] drm/msm: Ratelimit invalid-fence message
Git-commit: 7ad48d27a2846bfda29214fb454d001c3e02b9e7
Patch-mainline: v5.12-rc5
References: git-fixes

We have seen a couple cases where low memory situations cause something
bad to happen, followed by a flood of these messages obscuring the root
cause.  Lets ratelimit the dmesg spam so that next time it happens we
don't lose the kernel traces leading up to this.
