Fix bogus copying of data into userspace when HIDIOCGRDESC is issued.
HID-transport layer makes sure that dev->hid->rdesc is not larger than
HID_MAX_DESCRIPTOR_SIZE.

hidraw is an interface that is going to obsolete hiddev one
day.
Many userland applications are using libusb instead of using
kernel-provided hiddev interface. This is caused by various
reasons - the HID parser in kernel doesn't handle all the
HID hardware on the planet properly, some devices might require
its own specific quirks/drivers, etc.
hiddev interface tries to do its best to parse all the received
reports properly, and presents only parsed usages into userspace.
This is however often not enough, and that's the reason why
many userland applications just don't use hiddev at all, and
rather use libusb to read raw USB events and process them on
their own.
Another drawback of hiddev is that it is USB-specific.
hidraw interface provides userspace readers with really raw HID
reports, no matter what the low-level transport layer is (USB/BT),
and gives the userland applications all the freedom to process
the HID reports in a way they wish to.

The hiddev driver currently lacks 32bit ioctl compatibility, so
if you're running with a 64bit kernel and 32bit userspace, it won't
work.
I'm pretty sure that the only thing missing is a compat_ioctl
implementation as all structs have fixed size fields.
With this change I can use revoco to configure my MX Revolution mouse.

This patch fixes the problem, that Japanese MacBook doesn't recognize some keys
like '\'(yen, or backslash), '|'(pipe), and '_'(underscore).
It is due to that MacBook JIS keyboard (jp106) sends wrong report descriptor.
It saids "logical maximum = 0x65", so Keyboard.0089 is mapped to Key.Unknown,
while it should be accepted as Key.Yen.

- added KERN_DEBUG to output lines
- fixed preffered -> preferred typo
- added const to char *'s
Also, exported symbol hid_resolv_event is unused by the current
kernel tree and perhaps should be removed.

The infrared remote receiver found in the SantaRosa MacBookPro
laptops (MacBookPro3,1) need to be forced to expose a HIDDEV
interface (instead of HIDINPUT) so that lirc can access it using
the 'macmini' driver.
The patch below adds the required quirk for forcing the HIDDEV
interface to be activated (HID_QUIRK_HIDDEV) and introduces a new
quirk which forces the HIDINPUT interface to be ignored
(HID_QUIRK_IGNORE_HIDINPUT).
Note that Apple calls this receiver 'IRController4' (info taken
from Apple's driver Info.plist). Older Mac{Book,Mini,Pro}s seem
to all use the 'IRController1' device (USB id 05ac:8240) which
doesn't need those quirks.

Current HID layer does not report usage codes to the input layer. This feature
was previously removed, because it caused unnecessary storm of events in cases
of positioning devices, etc.
This patch adds reporting of usage codes as EV_MSC events only for key events.
We issue the EV_MSC event only if the state of the key corresponding to the
given code has changed, so that we don't report usages that are sent in every
report even if the state hasn't changed (for example Shift/Caps Lock/...
states as sent by various keyboards).
This functionality is required at least by KeyTouch in order to provide
convenient means for remapping the usage codes.

We have to ignore all non-LED usages in output fields if the
report descriptor of the device specifies any. If we don't do
so, the devices which contain the same usages both in input and
output reports with different parameters will mess things up. In
hid-input, we currently care only for the input usages, with exception
for LEDs. All other output usages should be properly handled by
appropriate force-feedback driver.

This keyboard emits a few usages that are not handled properly by
hid-input.
The usages from MSVENDOR page are colliding with Chicony Tactical
Pad device, so we have to distinguish in runtime. Ugly ...
Also, the buttons 1-5 have to be handled in a non-standard way,
as they are emitted by the keyboard in a bitfield-like fashion, but
the field is not presented as bit-field by the keyboard. The keys can't
be pressed simultaneously, so the handling we have is correct.
This patch also extends hid_keyboard[] with KPLeftParenthesis and
KPRightParenthesis as defined by Keyboard page in HUT 1.12. The
corresponding usages are also emitted by this keyboard.
