xf86_platform_devices[i].pdev may be NULL in cases we fail to parse the busid in config_udev_odev_setup_attribs() (see also [1], [2]) such as when udev does not give use ID_PATH. This in turn leads to platform_find_pci_info() being not called and pdev being NULL.

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.
