| |
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().
