Merge tag 'driver-core-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2017-07-04T03:27:48+00:00

Pull driver core updates from Greg KH:
 "Here is the big driver core update for 4.13-rc1.

  The large majority of this is a lot of cleanup of old fields in the
  driver core structures and their remaining usages in random drivers.
  All of those fixes have been reviewed by the various subsystem
  maintainers. There's also some small firmware updates in here, a new
  kobject uevent api interface that makes userspace interaction easier,
  and a few other minor things.

  All of these have been in linux-next for a long while with no reported
  issues"

usbip: Fix uninitialized variable bug in vhci

2017-06-27T15:57:50+00:00

The patch 03cd00d538a6: "usbip: vhci-hcd: Set the vhci structure up
to work" introduced a bug which uses a vairable without initialization
in error handling code. Fix it.

usbip: vhci-hcd: Clean up the code by adding a new macro

2017-06-13T08:51:10+00:00

Each vhci has 2*VHCI_HC_PORTS ports, in which VHCI_HC_PORTS
ports are HighSpeed (or below), and VHCI_HC_PORTS are SuperSpeed.
This new macro VHCI_PORTS reflects this configuration.

usbip: vhci-hcd: Add USB3 port status bits

2017-06-13T08:51:10+00:00

As USB3 has (slightly) different bit meanings in the port
status. Add a new status bit array for USB3.

usbip: vhci-hcd: Add USB3 SuperSpeed support

2017-06-13T08:51:10+00:00

This patch adds a USB3 HCD to an existing USB2 HCD and provides
the support of SuperSpeed, in case the device can only be enumerated
with SuperSpeed.

The bulk of the added code in usb3_bos_desc and hub_control to support
SuperSpeed is borrowed from the commit 1cd8fd2887e162ad ("usb: gadget:
dummy_hcd: add SuperSpeed support").

With this patch, each vhci will have VHCI_HC_PORTS HighSpeed ports
and VHCI_HC_PORTS SuperSpeed ports.

usbip: vhci-hcd: Rework vhci_hcd_init

2017-06-13T08:51:10+00:00

A vhci struct is added as the platform-specific data to the vhci
platform device, in order to get the vhci by its platform device.
This is done in vhci_hcd_init().

usbip: vhci-hcd: Move VHCI platform device into vhci struct

usbip: vhci-hcd: Add vhci struct

2017-06-13T08:51:09+00:00

In order to support SuperSpeed devices, a USB3 HCD is added to
share the USB2 HCD. As a result, a VHCI is composed of two
vhci_hcds associated with the two HCDs respectively. So we add
another level of abstraction, vhci, and thus this vhci structure.
