[U-Boot] [PATCH 1/2] usb: fix for USB_ST_STALLED status reporting in ehci_submit_async()

[Remy Bohmer]

Hi,

2010/11/2 Anatolij Gustschin <agust at denx.de>:
> Checking the status field of the qTD token in the current code
> do not take into acount cases where endpoint stall (halted) bit
> is set together with XactErr status bit. As a result clearing
> stall on an endpoint won't be done if this status bit was also
> set. Check for halted bit and report USB_ST_STALLED status
> if the host controller also indicates endpoit stall condition.

Applied to u-boot-usb

Thanks.
