From 088351a7e50b7f14cda9520bcb8a7896e226aa36 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Fri, 23 Mar 2012 15:43:45 +0100 Subject: [PATCH] usb-ehci: fix ehci_child_detach Looks like a cut+paste bug from ehci_detach. When the device itself is detached from a ehci port (ehci_detach op) we have to clear the device pointer for the companion port too. When a device gets removed from a downstream port of a usb hub (ehci_child_detach op) the ehci port where the usb hub is plugged in is not affected.
