| Subject: USB: xHCI: re-initialize cmd_completion |
| |
| 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(). |
