From: Mathias Nyman <[email protected]> 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: [email protected] Signed-off-by: Mathias Nyman <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]> --- 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 4dedc822237fc..39efbcf63c11d 100644 --- a/drivers/usb/host/xhci.h +++ b/drivers/usb/host/xhci.h @@ -716,7 +716,7 @@ 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
