From dcabc76fa9361186e6b88c30a68db8fa9d5b4a1c Mon Sep 17 00:00:00 2001 From: Lu Baolu Date: Thu, 5 Oct 2017 11:21:43 +0300 Subject: [PATCH] usb: xhci: Return error when host is dead in xhci_disable_slot() xhci_disable_slot() is a helper for disabling a slot when a device goes away or recovers from error situations. Currently, it returns success when it sees a dead host. This is not the right way to go. It should return error and let the invoker know that disable slot command was failed due to a dead host. Fixes: f9e609b82479 ("usb: xhci: Add helper function xhci_disable_slot().")
