HID: fix oops during suspend of unbound HID devices 
Usbhid structure is allocated on start invoked only from probe
of some driver. When there is no driver, the structure is null
and causes null-dereference oopses.

Fix it by allocating the structure on probe and disconnect of
the device itself. Also make sure we won't race between start
and resume or stop and suspend respectively.

HID: add hid_type to general hid struct 
Add type to the hid structure to distinguish to which device type
(now only mouse) we are talking to. Needed for per device type ignore
list support.

Note: this patch leaves the type as unknown for bluetooth devices,
there is not support for this in the hidp code.

HID: fix a lockup regression when using force feedback on a PID device 
Commit 8006479c9b introduced a spinlock in
input_dev->event_lock, which is locked when handling input events.
However, the hid-pidff driver sleeps when handling events as it waits for
reports being sent to the device before changing the report contents
again.
This causes a system lockup when trying to use force feedback with a PID
device, a regression introduced in 2.6.24 and 2.6.23.15.

Fix it by extracting the raw report data from struct hid_report
immediately when hid_submit_report() is called, therefore allowing
drivers to change the contents of struct hid_report immediately without
affecting the already-queued transfer.

In hid-pidff, re-add the removed usbhid_wait_io() to
pidff_erase_effect() instead, to prevent a full report queue from causing
the submission to fail, thus not freeing up device memory.
pidff_erase_effect() is not called while dev->event_lock is held.

HID: split Numlock emulation quirk from HID_QUIRK_APPLE_HAS_FN. 
Since 2.6.25 the HID_QUIRK_APPLE_HAS_FN quirk is enabled even for
non-laptop Apple keyboards of the Aluminium series. The USB version of
these don't need Numlock emulation, like the laptop (and Aluminium
Wireless) do, as they have a proper keypad.

This patch splits the Numlock emulation for Apple keyboards in a
different quirk flag, so that it can be enabled for all the keyboards
but the Aluminium USB ones.

If the Numlock emulation is enabled for Aluminium USB keyboards, the
JKL and UIO keys become the numeric pad, and the rest of the keyboard
is disabled, included the key used to disable Numlock.

Additionally, these keyboard should not have a Numlock at all, as the
Numlock key is instead replaced by the 'Clear' key as usual for Apple
USB keyboards.

HID: quirk for MS Wireless Desktop Receiver (model 1028) 
Microsoft's wireless desktop receiver (Model 1028) has a bug in the report
descriptor -- namely, in four seperate places it uses USAGE_MIN and _MAX when
it quite obviously doesn't intend to.

In other words, it reports that it has pretty much _everything_ in 'consumer'
and 'generic desktop'.  And then the X evdev driver believes I have a mouse
with 36 absolute axes and a huge pile of keys and buttons, when I in fact,
should have zero.  255/256 in three of the cases, and 0-1024 in another.

This patch fixes the report descriptor of this device before it enters the HID
parser.

HID: fixup fullspeed interval on highspeed Afatech DVB-T IR kbd 
Many vendors highspeed devices give erroneously fullspeed interval value in
endpoint descriptor for interrupt endpoints. This quirk fixes up that by
recalculating the right value for highspeed device.

At the time of hid configuration this quirk calculates which highspeed interval
value gives same interval delay as, or next smaller then, what it would be if
the original value would be interpreted as fullspeed value. In subsequent urbs
that new value is used instead.

Forming the 'hid->name' in usb_hid_config() was moved up to accommodate more
descriptive printk reporting the fixup.

In this patch the quirk is set for one such device: Afatech DVB-T 2 infrared
HID-keyboard. It reports value 16 which means 4,069s in highspeed while
obviously 16ms was intended. In this case quirk calculates new value to be 8
which gives when interpreted as highspeed value 16ms as wanted. The behavior of
the device was verified to be what expected both before and after the patch.

HID: Support Samsung IR remote 
Samsung USB remotes (0419:0001) are rejected by kernel 2.6.23, because the
report descriptor from the remote contains a 48 bit HID report field. HID 1.11
states: Fields may span at most 4 bytes.

This patch, based on 2.6.23, fixes this by modifying the internal report
descriptor in hid-quirks.c. Additional user space support (e.g. LIRC) is
required to fetch the information from the hiddev interface.

The burden to reconstruct the data is moved into userspace (lirc through hiddev).
There is no need to set HID_QUIRK_HIDDEV quirk, as the device has also output
applications, which trigger the creation of hiddev device automatically.

HID: add full support for Genius KB-29E 
Genius KB-29E has broken report descriptor, which causes some of the
Consumer usages to appear incorrectly as Button usages. We fix it by
fixing the report descriptor before it is being parsed.

Also a few of the keys violate the HUT standard, so they need a special
handling. They currently fall into "Reserved" range as per HUT 1.12.
