Fixed bug 4624 - KMS/DRM fails on FreeBSD because /dev/dri/card* nodes are symlinks 

Jan Martin Mikkelsen

Patch to scan /dev/dri based on names rather than file type

Loading KMS/DRM on FreeBSD fails because the "available" code in the driver checks for character device nodes under /dev/dri and the /dev/dri/card* files are symlinks rather than device nodes nodes on FreeBSD. The symlink points to /dev/drm/0.

The attached patch counts /dev/dri/card* entries rather than directory entries which are character devices.
