    Subject[071/156] USB: xHCI: re-initialize cmd_completion
    2.6.33-stable review patch.  If anyone has any objections, please let us know.

    ------------------

    From: Andiry Xu <andiry.xu@amd.com>

    commit 1d68064a7d80da4a7334cab0356162e36229c1a1 upstream.

    When a signal interrupts a Configure Endpoint command, the cmd_completion used
    in xhci_configure_endpoint() is not re-initialized and the
    wait_for_completion_interruptible_timeout() will return failure. Initialize
    cmd_completion in xhci_configure_endpoint().
