The patch seems reasonable but could you please describe where you saw this
issue? It seems 'igt_devices_scan(true)' (called with force == true) will
get past this issue. Not too familiar with igt_devices_scan() usage so
copying some more people.

Also I am not sure why igt_devices_scan() doesn't simply do this:

void igt_devices_scan(bool force)
{
	if (force && igt_devs.devs_scanned) {
		igt_devices_free();

		/* Not needed after this patch */
		igt_devs.devs_scanned = false;
	}



Thanks.
