sys/dev/pci/drm: drm_drv.c
Log message:
Support for "control" nodes was removed from the drm subsystem some time
ago, but some code in drmopen() remained which means that opening a drm
device node with a minor that matches the range for the "control" nodes
will hit a kernel assertion. A similar issue exists for "render" nodes
corresponding to a driver that only supports KMS (such as rkdrm(4)).
Add checks to see if the minor is valid and return ENXIO if that isn't the
case to prevent a kernel crash.
