Date: Sat, 17 Oct 2015 19:05:29 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Roger Quadros <rogerq@...com>, Mathias Nyman <mathias.nyman@...ux.intel.com> Subject: [PATCH 3.10 25/54] usb: xhci: Clear XHCI_STATE_DYING on start 3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Roger Quadros <rogerq@...com> commit e5bfeab0ad515b4f6df39fe716603e9dc6d3dfd0 upstream. For whatever reason if XHCI died in the previous instant then it will never recover on the next xhci_start unless we clear the DYING flag.
