  "message": "USB: add check to detect host controller hardware removal\n\nThis patch (as1391) fixes a problem that can occur when USB host\ncontroller hardware is hot-unplugged.  If no interrupts are generated\nby the unplug then the HCD may not realize that the controller is\ngone, and the subsequent unbind may hang waiting for interrupts that\nnever arrive.\n\nThe solution (for PCI-based controllers) is to call the HCD\u0027s\ninterrupt handler at the start of usb_hcd_pci_remove().  If the\nhardware is gone, the handler will realize this when it tries to read\nthe controller\u0027s status register.\n\nSigned-off-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n",
