[PATCH AUTOSEL 5.10 15/33] drm/msm: Ratelimit invalid-fence message

[Sasha Levin]

From: Rob Clark <robdclark@xxxxxxxxxxxx>

[ Upstream commit 7ad48d27a2846bfda29214fb454d001c3e02b9e7 ]

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.
