[PATCH 13/45] USB: xHCI: re-initialize cmd_completion

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Andiry Xu <andiry.xu@xxxxxxx>

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().
