We can't call hid_free_buffers() when the underlying usbhid_device
has already been freed.

Add forgotten freeing of usbhid_device structure.

If, in usb_hid_configure(), we fail to allocate storage for 'usbhid',
 "if (!(usbhid = kzalloc(sizeof(struct usbhid_device), GFP_KERNEL)))",
then we'll jump to the 'fail:' label where we have this code:
        usb_free_urb(usbhid->urbin);
        usb_free_urb(usbhid->urbout);
        usb_free_urb(usbhid->urbctrl);
Since we got here because we couldn't allocate storage for 'usbhid',
what we have here is a NULL pointer dereference - ouch...

This patch solves that little problem by adding a new
'fail_no_usbhid:' label after the problematic calls to
usb_free_urb() and jumps to that one instead, in the problem case.

Some of ASUS' notebooks (e.g G Series) include a tiny oled display, which is
attached to an internal USB bus. Unfortunatly the device reports a wrong
DeviceDescriptor and is therefore identified as a HID device...

This patch adds the entire range of Logitech's ProductIDs that are reserved
for their Harmony remotes. The in-kernel HID driver can't do anything with
these, and now there is a GPL user-space application that can handle them:

The IR sensor in some newer Apple computers has no other
driver in the kernel, yet. However, the macmini driver in lirc
requires a HID device for the IR sensor.

This patch (as918) introduces a new USB driver method: reset_resume.
It is called when a device needs to be reset as part of a resume
procedure (whether because of a device quirk or because of the
USB-Persist facility), thereby taking over a role formerly assigned to
the post_reset method.  As a consequence, post_reset no longer needs
an argument indicating whether it is being called as part of a
reset-resume.  This separation of functions makes the code clearer.

In addition, the pre_reset and post_reset method return types are
changed; they now must return an error code.  The return value is
unused at present, but at some later time we may unbind drivers and
re-probe if they encounter an error during reset handling.

The existing pre_reset and post_reset methods in the usbhid,
usb-storage, and hub drivers are updated to match the new
requirements.  For usbhid the post_reset routine is also used for
reset_resume (duplicate method pointers); for the other drivers a new
reset_resume routine is added.  The change to hub.c looks bigger than
it really is, because mark_children_for_reset_resume() gets moved down
next to the new hub_reset_resume() routine.

A minor change to usb-storage makes the usb_stor_report_bus_reset()
routine acquire the host lock instead of requiring the caller to hold
it already.

This patch (as886) adds the controversial USB-persist facility,
allowing USB devices to persist across a power loss during system
suspend.

The facility is controlled by a new Kconfig option (with appropriate
warnings about the potential dangers); when the option is off the
behavior will remain the same as it is now.  But when the option is
on, people will be able to use suspend-to-disk and keep their USB
filesystems intact -- something particularly valuable for small
machines where the root filesystem is on a USB device!
