We used earlier to check for ep->ep.desc to figure out if this ep is
already enabled and if so, abort.
Ido Shayevitz removed the usb_endpoint_descriptor from private udc
structure 5a6506f00 ("usb: gadget: Update at91_udc to use
usb_endpoint_descriptor inside the struct usb_ep") but did not fix up
the ep_enable condition because _now_ the member is always true and we
can't check if this ep is enabled twice.Cc: Ido Shayevitz <[email protected]> Signed-off-by: Sebastian Andrzej Siewior <[email protected]> --- drivers/usb/gadget/at91_udc.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/drivers/usb/gadget/at91_udc.c b/drivers/usb/gadget/at91_udc.c index 5fd61e2..22865dd 100644 --- a/drivers/usb/gadget/at91_udc.c +++ b/drivers/usb/gadget/at91_udc.c @@ -475,8 +475,7 @@ static int at91_ep_enable(struct usb_ep *_ep, unsigned long flags; if (!_ep || !ep - || !desc || ep->ep.desc - || _ep->name == ep0name + || !desc || _ep->name == ep0name || desc->bDescriptorType != USB_DT_ENDPOINT || (maxpacket = usb_endpoint_maxp(desc)) == 0 || maxpacket > ep->maxpacket) { @@ -530,7 +529,6 @@ ok: tmp |= AT91_UDP_EPEDS; __raw_writel(tmp, ep->creg); - ep->ep.desc = desc; ep->ep.maxpacket = maxpacket; /* -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
