Thanks!
Your fix is correct, although partial: the same bug appears again in the free()
a couple lines below.
I've added it as part of your patch and pushed it:

    xf86drm: Fix segmentation fault while parsing device info

    This fixes a bug, which was introduced with commit ee798b98
    "xf85drm: de-duplicate drmParse{Platform.Host1x}{Bus,Device}Info".
    where accessing *compatible[i] with i>0 results in a segfault.
