Subject: xhci: fix finding correct bus_state structure for USB 3.1 hosts
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5e425d575cd83c9de5662378e78b90f2e39712dc;p=pandora-kernel.git

xhci: fix finding correct bus_state structure for USB 3.1 hosts

commit 5a838a13c9b4e5dd188b7a6eaeb894e9358ead0c upstream.

xhci driver keeps a bus_state structure for each hcd (usb2 and usb3)

The structure is picked based on hcd speed, but driver only compared
for HCD_USB3 speed, returning the wrong bus_state for HCD_USB31 hosts.

This caused null pointer dereference errors in bus_resume function.
