  "message": "USB: mutual exclusion for EHCI init and port resets\n\nThis patch (as999) fixes a problem that sometimes shows up when host\ncontroller driver modules are loaded in the wrong order.  If ehci-hcd\nhappens to initialize an EHCI controller while the companion OHCI or\nUHCI controller is in the middle of a port reset, the reset can fail\nand the companion may get very confused.  The patch adds an\nrw-semaphore and uses it to keep EHCI initialization and port resets\nmutually exclusive.\n\nSigned-off-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nAcked-by: David Brownell \u003cdavid-b@pacbell.net\u003e\nCc: David Miller \u003cdavem@davemloft.net\u003e\nCc: Dely L Sy \u003cdely.l.sy@intel.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n",
