Subject: drm/etnaviv: remove -EAGAIN handling from submit path
Git-commit: b7b17e5cec541f58131f4a7963bbe3448f0a9c00
Patch-mainline: v4.16-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Now that the userptr BO handling doesn't rely on the userspace restarting
the submit after object population, there is no need to special case the
-EAGAIN return value anymore.
