USB: serial: io_edgeport: fix NULL-deref at open
Fix NULL-pointer dereference when initialising URBs at open should a non-EPIC device lack a bulk-in or interrupt-in endpoint. Unable to handle kernel NULL pointer dereference at virtual address 00000028 ... PC is at edge_open+0x24c/0x3e8 [io_edgeport] Note that the EPIC-device probe path has the required sanity checks so this makes those checks partially redundant. Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Cc: stable <stable@vger.kernel.org> Signed-off-by: Johan Hovold <johan@kernel.org>
