This set contains a few fixes for formatting issues and compile warnings
in UWB. Some of the changes for lines over 80 chars required pulling
deeply nested code into separate functions which makes that patch look
more significant than it really is.

Alan and Rajaram, thanks for your help. I have not looked at Linux
kernel builds in this detail before. I have been trying to recompile
modules for the Linaro 3.5 kernel that we adopted last year. I can see
now there is no choice but to start building kernels and modules
together. I have

Once usb-acpi has set the port's connect type the usb_device's
->removable attribute can be set in the standard location
set_usb_port_removable().
This also changes behavior in the case where the firmware says that the
port connect type is unknown. In that case just use the default setting

A hub indicates whether it supports per-port power control via the
wHubCharacteristics field in its descriptor. If it is not supported
a hub will still emulate ClearPortPower(PORT_POWER) requests by
stopping the link state machine. However, since this does not save
power do not bother suspending.
Changes since v7 [1]:
* Added patch 8 "usb: make usb_port flags atomic"
* Added patch 15 "usb: hub_handle_remote_wakeup() depends on
CONFIG_PM_RUNTIME=y"
* Fixed patch 16 "usb: resume (wakeup) child device when port is powered
on"
- added USB_PORTDEV_WAKE flag to force usb_remote_wakeup() i
The current port name "portX" is ambiguous. Before adding more port
messages rename ports to "-portX"
This is an ABI change, but the suspicion is that it will go unnoticed as
the port power control implementation has been broken since its
introduction. If however, someone was relying on the old
Given that root hub port peers are already established, external hub peer
ports can be determined by traversing the device topology:
1/ ascend to the parent hub and find the upstream port_dev
2/ walk ->peer to find the peer port
3/ descend to the peer hub via ->child
4/ find the port with the m
ACPI identifies peer ports by setting their 'group_token' and
'group_position' _PLD data to the same value. If a platform has tier
mismatch [1] , ACPI can override the default (USB3 defined) peer port
association for internal hubs. External hubs follow the default peer
association scheme.
Locati
The usb topology after this change will have symlinks between usb3 ports
and their usb2 peers, for example:
usb2/2-1/2-1:1.0/2-1-port1/peer => ../../../../usb3/3-1/3-1:1.0/3-1-port1
usb2/2-1/2-1:1.0/2-1-port2/peer => ../../../../usb3/3-1/3-1:1.0/3-1-port2
usb2/2-1/2-1:1.0/2-1-port3/peer => ../../.
Unconditionally wake up the child device when the power session is
recovered.
This address the following scenarios:
1/ The device may need a reset on power-session loss, without this
change port power-on recovery exposes khubd to scenarios that
usb_port_resume() is set to handle. Prior to
Three reasons:
1/ It's an invalid operation on usb3 ports
2/ There's no guarantee of when / if a usb2 port has entered an error
state relative to PORT_POWER request
3/ The port is active / powered at this point, so khubd will clear it as
a matter of course

Before we add another 2 bitfields to the port state, convert it to an
unsigned long and use bitops helpers to manipulate it. This later
enables setting bits to request action without worrying about colliding
updates. In particular, a flag to request that the child device be
woken up when the port
