Jiri Slaby a7ef7d1f5e PCI: hotplug/cpqphp, fix NULL dereference ... There are devices out there which are PCI Hot-plug controllers with compaq PCI IDs, but are not bridges, hence have pdev->subordinate NULL. But cpqphp expects the pointer to be non-NULL. Add a check to the probe function to avoid oopses like: BUG: unable to handle kernel NULL pointer dereference at 00000050 IP: [<f82e3c41>] cpqhpc_probe+0x951/0x1120 [cpqphp] *pdpt = 0000000033779001 *pde = 0000000000000000 ... The device here was: 00:0b.0 PCI Hot-plug controller [0804]: Compaq Computer Corporation PCI Hotplug Controller [0e11:a0f7] (rev 11) Subsystem: Compaq Computer Corporation Device [0e11:a2f8] Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: Greg KH <greg@kroah.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>		2010-06-11 13:10:21 -07:00
