Subject: [PATCH] drm/etnaviv: relax submit size limits
Git-commit: e3d26528e083e612314d4dcd713f3d5a26143ddc
Patch-mainline: v5.17-rc2
References: git-fixes

While all userspace tried to limit commandstreams to 64K in size,
a bug in the Mesa driver lead to command streams of up to 128K
being submitted. Allow those to avoid breaking existing userspace.
