drivers/gpu/drm/radeon/mkregtable.c:parser_auth() almost always remembers to fclose(file) before returning, but it misses two spots.
This is not really important since the process will exit shortly after and thus close the file for us, but being explicit prevents static analysis tools from complaining about leaked memory and missing fclose() calls and it also seems to be the prefered style of the existing code to explicitly close the file.
So, here's a patch to add the two missing fclose() calls.
