HID: remove compat stuff
This removal was scheduled and there is no problem with later
distros to adapt for the new bus, thanks to aliases.

module-init-tools map files are deprecated nowadays, so that
the patch which introduced hid ones into the m-i-t won't be
accepted and hence there is no reason for leaving compat stuff in.

HID: fix race between usb_register_dev() and hiddev_open()
upon further thought this code is still racy.

	retval = usb_register_dev(usbhid->intf, &hiddev_class);

here you open a window during which open can happen

	if (retval) {
		err_hid("Not able to get a minor for this device.");
		hid->hiddev = NULL;
		kfree(hiddev);
		return -1;
	} else {
		hid->minor = usbhid->intf->minor;
		hiddev_table[usbhid->intf->minor - HIDDEV_MINOR_BASE] = hiddev;

and will fail because hiddev_table hasn't been updated

The obvious fix of using a mutex to guard hiddev_table doesn't work because
usb_open() and usb_register_dev() take minor_rwsem and we'd have an AB-BA
deadlock. We need a lock usb_open() also takes in the right order and that leaves
only one option, BKL. I don't like it but I see no alternative.

Once the usb_open() implements something better than lock_kernel(), we could also
do so.

HID: bring back possibility to specify vid/pid ignore on module load
When hid quirks were converted to specialized driver, the HID_QUIRK_IGNORE
has been moved completely, as the hid_ignore_list[] has been moved into the
generic code.

However userspace already got used to the possibility that modprobing
usbhid with

makes the device ignored by usbhid driver. So keep this quirk flag in place

HID: autosuspend support for USB HID
This uses the USB busy mechanism for aggessive autosuspend of USB
HID devices. It autosuspends all opened devices supporting remote wakeup
after a timeout unless

- output is being done to the device
- a key is being held down (remote wakeup isn't triggered upon key release)
- LED(s) are lit
- hiddev is opened

As in the current driver closed devices will be autosuspended even if they
don't support remote wakeup.

The patch is quite large because output to devices is done in hard interrupt
context meaning a lot a queuing and locking had to be touched. The LED stuff
has been solved by means of a simple counter. Additions to the generic HID code
could be avoided. In addition it now covers hidraw. It contains an embryonic
version of an API to let the generic HID code tell the lower levels which
capabilities with respect to power management are needed.

Rationalize fasync return values
Most fasync implementations do something like:

     return fasync_helper(...);

But fasync_helper() will return a positive value at times - a feature used
in at least one place.  Thus, a number of other drivers do:

     err = fasync_helper(...);
     if (err < 0)
             return err;
     return 0;

In the interests of consistency and more concise code, it makes sense to
map positive return values onto zero where ->fasync() is called.

HID: fix waitqueue usage in hiddev
DECLARE_WAITQUEUE doesn't initialize the wait descriptor's task_list
to 'empty' but to zero.

prepare_to_wait() will not enqueue the descriptor to the waitqueue and
finish_wait() will do list_del_init() on a list head that contains
NULL pointers, which oopses.

This was introduced by 079034073 "HID: hiddev cleanup -- handle all
error conditions properly".

The prior code used an unconditional add_to_waitqueue() which didn't
care about the wait descriptor's list head and enqueued the thing
unconditionally.

The new code uses prepare_to_wait() which DOES check the prior list
state, so use DEFINE_WAIT instead.

HID: blacklist Powercom USB UPS
For quite some time users with various UPSes from Powercom were forced to play
magic with bind/unbind in /sys in order to be able to see the UPSes.  The
beasts does not work as HID devices, even if claims to do so.  cypress_m8
driver works with the devices instead, creating a normal serial port with which
normal UPS controlling software works.

The manufacturer confirmed the upcoming models with proper HID support will
have different device IDs.  In any way, it's wrong to have two completely
different modules for one device in kernel.

Blacklist the device in HID (add it to hid_ignore_list) to stop this mess,
finally.

USB: change interface to usb_lock_device_for_reset()
This patch (as1161) changes the interface to
usb_lock_device_for_reset().  The existing interface is apparently not
very clear, judging from the fact that several of its callers don't
use it correctly.  The new interface always returns 0 for success and
it always requires the caller to unlock the device afterward.

The new routine will not return immediately if it is called while the
driver's probe method is running.  Instead it will wait until the
probe is over and the device has been unlocked.  This shouldn't cause
any problems; I don't know of any cases where drivers call
usb_lock_device_for_reset() during probe.

HID: add proper support for pensketch 12x9 tablet
The Genius PenSketch 12x9 tablet has a puck (labeled a

the tablet appears to be a single input device that reports the
wrong axis information in /proc/bus/input/devices, and sends
incorrect events (e.g. ABS_Z instead of ABS_Y). This information
confuses the X evdev driver and makes the device impossible to
use.

The quirk fixes events and splits the device into multiple input
event devices so that at least the puck is useful.

HID: hiddev cleanup -- handle all error conditions properly
This is a cleanup of hiddev and fixes the following issues:

- thread safety by locking in read & ioctl, introducing a per device mutex
- race between ioctl and disconnect, introducing a flag and locking
  in form of a per low level device mutex
- race between open and other methods, making sure only successfully
  opened devices are put on the list, changing order of events
- range checking both upper and lower limits of the minor range
- make sure further calls to open fail for unplugged devices even if
  the device still has opened files
- error checking for low level open
- possible loss of wakeup events, using standard waiting macros
- race in initialisation by moving registration after full initialisation

HID: force feedback driver for GreenAsia 0x12 PID
I have implemented Force Feedback driver for another "GreeAsia" based device
(0e8f:0012 "GreenAsia Inc. USB Joystick"). The functionality was tested with
MANTA Warior MM816 and SpeedLink Strike2 SL-6635 and fftest software -
everything seems to work right.

HID: switch specialized drivers from "default y" to !EMBEDDED
Fix the obnoxious "default y" for all the "special" HID code, which forces folk
with EMBEDDED defined to manually override that inappropriate default for
almost 20 choices.  The general policy is against "default y"; it should apply
here too.

HID: set proper dev.parent in hidraw
We need to properly set parent of the hidraw device (which is the
corresponding physical device itself) in order to hidraw devices not
end up under virtual device tree.

HID: add dynids facility
Allow adding new devices to the hid drivers on the fly without
a need of kernel recompilation.

Now, one can test a driver e.g. by:
echo 0003:045E:00F0.0003 > ../generic-usb/unbind
echo 0003 045E 00F0 > new_id
from some driver subdir.

We might sleep, so no problem to use GFP_KERNEL.

While at it bring the function to coding style.
