2.6.33-stable review patch. If anyone has any objections, please let us know.

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

From: Andiry Xu <andiry.xu(a)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().
