Git-commit: b6097727ae57dc782900e5955ac03c5d6158b28d
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
With this we can drop the final kfree from the release function.
I also noticed that cirrus forgot to call drm_dev_fini().
v2: Don't call kfree(cirrus) after we've handed overship of that to
drm_device and the drmm_ stuff.
