Povilas Kanapickas 2f53d1cf73 config: Fix platform busid parsing when there is no ID_PATH prop 
On at least Lenovo Thinkpad E585 udev does not have ID_PATH property for
the drm node (see
https://gitlab.freedesktop.org/xorg/xserver/-/issues/993). While this is
likely udev bug, this causes the device to be not recognized as
attribs->busid is NULL, which causes platform_find_pci_info to be not
called and corresponding xf86_platform_devices[i]->pdev to be NULL.

At this moment pdev being NULL will cause a crash, but this is a
different bug.

Fixes: https://gitlab.freedesktop.org/xorg/xserver/-/issues/993

X Server

The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.

Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server

All questions regarding this software should be directed at the Xorg mailing list:
