Bug 1406: DRMUtil: Probe DRM device whether it has resources attached (and is the desired one)
First issue was that the proper DRM file had to be queries,
as Raspberry 4 may have two of them:
<--
/dev/dri/dri0
/dev/dri/dri0
/dev/dri/by-path/platform-fec00000.v3d-card -> ../card0
/dev/dri/by-path/platform-soc:gpu-card -> ../card1
-->
This patch attempts to probe all /dev/dri/card[0..99]
using this arbitrary range.
The test loop ends if:
- drmOpenFile succeeds and drmModeGetResources delivers non-null value
- the iterated probed file doesn't even exist
- 100 files has been tested ;-)
