Signed-off-by: Oliver Neukum <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]> Signed-off-by: Kamal Mostafa <[email protected]> [ gregkh: xhci: fix placement of call to usb_disabled() In the backport of 1eaf35e4dd592c59041bc1ed3248c46326da1f5f, the call to usb_disabled() was too late, after we had already done some allocation. Move that call to the top of the function instead, making the logic match what is intended and is in the original patch. ] Reported-by: Luis Henriques <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]> Signed-off-by: Kamal Mostafa <[email protected]> --- drivers/usb/host/xhci.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/drivers/usb/host/xhci.c b/drivers/usb/host/xhci.c index 2951ccb..c363a36 100644 --- a/drivers/usb/host/xhci.c +++ b/drivers/usb/host/xhci.c @@ -4857,6 +4857,9 @@ static int __init xhci_hcd_init(void) { int retval; + if (usb_disabled()) + return -ENODEV; + retval = xhci_register_pci(); if (retval < 0) { pr_debug("Problem registering PCI driver.\n"); @@ -4884,6 +4887,7 @@ static int __init xhci_hcd_init(void) BUILD_BUG_ON(sizeof(struct xhci_intr_reg) != 8*32/8); /* xhci_run_regs has eight fields and embeds 128 xhci_intr_regs */ BUILD_BUG_ON(sizeof(struct xhci_run_regs) != (8+8*128)*32/8); + return 0; unreg_pci: xhci_unregister_pci(); -- 1.9.1
