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@vger.kernel.org Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> --- drivers/usb/host/xhci.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
