From: Mathias Nyman <mathias.nyman@xxxxxxxxxxxxxxx> commit dceea67058fe22075db3aed62d5cb62092be5053 upstream. EP_STATE_MASK should be 0x7 instead of 0xf xhci spec 6.2.3 shows that the EP state field in the endpoint context data structure consist of bits [2:0]. The old value included a bit from the next field which fortunately is a RsvdZ region. So hopefully this hasn't caused too much harm Cc: stable@xxxxxxxxxxxxxxx Signed-off-by: Mathias Nyman <mathias.nyman@xxxxxxxxxxxxxxx> Link: https://lore.kernel.org/r/20200624135949.22611-2-mathias.nyman@xxxxxxxxxxxxxxx Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/usb/host/xhci.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/usb/host/xhci.h b/drivers/usb/host/xhci.h index db1af99d53bdb..8b52a7773bc84 100644 --- a/drivers/usb/host/xhci.h +++ b/drivers/usb/host/xhci.h @@ -718,7 +718,7 @@ struct xhci_ep_ctx { * 4 - TRB error * 5-7 - reserved */ -#define EP_STATE_MASK (0xf) +#define EP_STATE_MASK (0x7) #define EP_STATE_DISABLED 0 #define EP_STATE_RUNNING 1 #define EP_STATE_HALTED 2 -- 2.25.1
