If any userspace program has opened a keyboard device, the input core
de-activates the keyboard's LEDs upon suspend(). It does this by sending
individual EV_LED[LED_X]=0 events to the underlying device driver by
directly calling the driver's registered event() handler.
The usb-hid driver event() handler processes each request by immediately
attempting to submit a CTRL URB to turn off the LED. USB URB submission
is asynchronous. First the URB is added to the head of the ctrl queue.
Then, if the CTRL_RUNNING flag is false, the URB is submitted immediately
(and CTRL_RUNNING is set). If the CTRL_RUNNING flag was already true,
then the newly queued URB is submitted in the ctrl completion handler when
all previously submitted URBs have completed. When all queued URBs have
been submitted, the completion handler clears the CTRL_RUNNING flag.
In the 2-LED suspend case, at input suspend(), 2 LED event CTRL URBs get
queued, with only the first actually submitted. Soon after input
suspend() handler finishes, the usb-hid suspend() handler gets called.
Since this is NOT a PM_EVENT_AUTO suspend, the handler sets
REPORTED_IDLE, then waits for io to complete.
Unfortunately, this usually happens while the first LED request is
actually still being processed. Thus when the completion handler tries
to submit the second LED request it fails, since REPORTED_IDLE is
already set! This REPORTED_IDLE check failure causes the completion
handler to complete, however without clearing the CTRL_RUNNING flag.
This, in turn, means that the suspend() handler's wait_io() condition
is never satisfied, and instead it times out after 10 seconds, aborting
the original system suspend.
This patch changes the behavior to the following:
(1) allow completion handler to finish submitting all queued URBs, even if
REPORTED_IDLE is set. This guarantees that all URBs queued before the
hid-core suspend() call will be submitted before the system is
suspended.
(2) if REPORTED_IDLE is set and the URB queue is empty, queue, but
don't submit, new URB submission requests. These queued requests get
submitted when resume() flushes the URB queue. This is similar to the
existing behavior, however, any requests that arrive while the queue is
not yet empty will still get submitted before suspend.
(3) set the RUNNING flag when flushing the URB queue in resume().
This keeps URBs that were queued in (2) from colliding with any new
URBs that are being submitted during the resume process. The new URB
submission requests upon resume get properly queued behind the ones
being flushed instead of the current situation where they collide,
causing memory corruption and oopses.

Most of the parsing errors (typically resulting in device not being claimed
by HID subsystem at all) are reported only in debugging mode, which makes
root-causing problems with buggy devices unnecessarily more difficult.
Convert reporting of important HID report descriptor parsing errors to
be reported through hid_err() / hid_warn() instead of dbg_hid().

Some HID devices, such as my Bluetooth mouse, report their battery
strength as an event. Rather than passing it through as a strange
absolute input event, this patch registers it with the power_supply
subsystem as a battery, so that the device's Battery Strength can be
reported to usermode.
The battery appears in sysfs names
/sys/class/power_supply/hid-<UNIQ>-battery, and it is a child of the
battery-containing device, so it should be clear what it's the battery of.
Unfortunately on my current Fedora 16 system, while the battery does
appear in the UI, it is listed as a Laptop Battery with 0% charge (since
it ignores the "capacity" property of the battery and instead computes
it from the "energy*" fields, which we can't supply given the limited
information contained within the HID Report).
Still, this patch is the first step.

Genera Touch told us that 0001 is their single point device
and 0003 is the multitouch one. Apparently, we made the tests
someone having a prototype, and not the final product.
They said it should be safe to do the switch.
