This patch tries to identify which devices are able to accept
reset-resume handling, by checking that there is at least one
interface driver bound and that all of the drivers have a reset_resume
method defined.  If these conditions don't hold then during resume
processing, the device is logicall disconnected.

This is only a temporary fix.  Later on we will explicitly unbind
drivers that can't handle reset-resumes.

<content type='text'>
This patch (as1096) fixes an annoying problem: When a full-speed or
low-speed device is plugged into an EHCI controller, it fails to
enumerate at high speed and then is handed over to the companion
controller.  But usbcore logs a misleading and unwanted error message
when the high-speed enumeration fails.

The patch adds a new HCD method, port_handed_over, which asks whether
a port has been handed over to a companion controller.  If it has, the
error message is suppressed.

<title>USB: add all configs to the "descriptors" attribute</title>

<content type='text'>
This patch (as1094) changes the output of the "descriptors" binary
attribute.  Now it will contain the device descriptor followed by all
the configuration descriptors, not just the descriptor for the current
config.

Userspace libraries want to have access to the kernel's cached
descriptor information, so they can learn about device characteristics
without having to wake up suspended devices.  So far the only user of
this attribute is the new libusb-1.0 library; thus changing its
contents shouldn't cause any problems.

This should be considered for 2.6.26, if for no other reason than to
minimize the range of releases in which the attribute contains only the
current config descriptor.

Also, it doesn't hurt that the patch removes the device locking --
which was formerly needed in order to know for certain which config was
indeed current.

<title>USB: fix possible deadlock involving sysfs attributes</title>

<id>e16362a0c8d90e9adbfe477acbe32b021823fb22</id>
<content type='text'>
There is a potential deadlock when the usb_generic driver is unbound
from a device.  The problem is that generic_disconnect() is called
with the device lock held, and it removes a bunch of device attributes
from sysfs.  If a user task happens to be running an attribute method
at the time, the removal will block until the method returns.  But at
least one of the attribute methods (the store routine for power/level)
needs to acquire the device lock!

This patch (as1093) eliminates the deadlock by moving the calls to
create and remove the sysfs attributes from the usb_generic driver
into usb_new_device() and usb_disconnect(), where they can be invoked
without holding the device lock.

Besides, the other sysfs attributes are created when the device is
registered and removed when the device is unregistered.  So it seems
only fitting for the extra attributes to be created and removed at the
same time.

There is a race from when a device is created with device_create() and
then the drvdata is set with a call to dev_set_drvdata() in which a
sysfs file could be open, yet the drvdata will be NULL, causing all
sorts of bad things to happen.

This patch fixes the problem by using the new function,
device_create_drvdata().

<title>USB: create attributes before sending uevent</title>

This patch (as1087d) fixes a long-standing problem in usbcore: Device,
interface, and endpoint attributes aren't added until _after_ the
creation uevent has already been broadcast.

Unfortunately there are a few attributes which cannot be created that
early.  The "descriptors" attribute is binary and so must be created
separately.  The power-management attributes can't be created until
the dev/power/ group exists.  And the interface string can vary from
one altsetting to another, so it has to be created dynamically.
