From 1d68064a7d80da4a7334cab0356162e36229c1a1 Mon Sep 17 00:00:00 2001 From: Andiry Xu Date: Fri, 12 Mar 2010 17:10:04 +0800 Subject: USB: xHCI: re-initialize cmd_completion 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().
