Subject: Be a bit defensive in quirk_nvidia_ck804() so we don't risk dereferencing a NULL pdev.
From: Jesper Juhl <jesper.juhl@xxxxxxxxx>
pci_get_slot() may return NULL if nothing was found. quirk_nvidia_ck804()
does not check the value returned from pci_get_slot(), so it may end up
causing a NULL pointer deref.
