90ab5ee941 module_param: make bool parameters really bool (drivers & misc)
module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

c5a92aa3eb hid-input: add support for HID devices reporting Battery Strength
I've sent an email earlier asking for help with a GetFeature code, and now I
have a second patch on top of Jeremy's to provide the battery functionality
for devices that support reporting it.

If I understood correctly when talking to Jeremy he said his device
never actually reported the status as an input event (sorry if I didn't
understand it correctly), and after reading HID specs I believe it's
really because it was meant to be probed, I have an Apple Keyboard and
Magic Trackpad both bluetooth batteries operated, so using PacketLogger
I saw that Mac OSX always ask the battery status using the so called
GetFeature.

What my patch does is basically:
- store the report id that matches the battery_strength
- setup the battery if 0x6.0x20 is found, even if that is reported as a feature
  (as it was meant to be but only the MagicTrackpad does)
- when upower or someone access /sys/class/power_supply/hid-*/capacity it
  will probe the device and return it's status.

It works great for both devices, but I have two concerns:
- the report_features function has a duplicated code
- it would be nice if it was possible for specific drivers to provide their own
  probe as there might be some strange devices... (but maybe it's
already possible)

I've talked to the upower dev and he fixed it to be able to show the
right percentage.

Here how the uevent file (in /sys/class/power_supply/hid-*/) looks like:
POWER_SUPPLY_NAME=hid-00:22:41:D9:18:E7-battery
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_ONLINE=1
POWER_SUPPLY_CAPACITY=66
POWER_SUPPLY_MODEL_NAME=MacAdmin’s keyboard

f0befcd64b HID: usbhid: hid-core: submit queued urbs before suspend
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.

4f5ca836be HID: hid-input: add support for HID devices reporting Battery Strength
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.

1b723e8dc8 HID: multitouch: correct eGalax a001 protocol
This device use another protocol while sending the events.
It's the same as the one described as "serial" by Microsoft.
We are keeping here the sn_move and sn_pressure parameters for

2261bb9ff0 HID: multitouch: cleanup eGalax quirks
The previous implementation of eGalax protocol was not satisfying as
we had to manually set x/y ranges as they were corrupted after reading
the report descriptor.
Indeed, the report descriptor provided a stylus input interface which
override the correct values.

This patch omits this input, thus leaving the correct value untouched,
and the MT_QUIRK_EGALAX_XYZ_FIXUP not required anymore.
