From 5eaec968f3377c20e7da49f8e3aef1d874a0591b Mon Sep 17 00:00:00 2001 From: Roger Quadros Date: Mon, 21 Sep 2015 17:46:13 +0300 Subject: usb: xhci: Clear XHCI_STATE_DYING on start 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.
