==Bug detailed description==
It happens on all platform with -fixes, -queued and -nightly kernel.
New case gem_userptr_blits/process-exit-gtt's return code is 0, the result
shows pass, but the pid still keep in /sys/kernel/debug/dri/0/clients.
Run this case then run other cases, they will report "other drm clients
running!" and fail.
[root@x-sgb4 tests]# cat /sys/kernel/debug/dri/0/clients
