It is not a good idea to try to fit all types of applications in the
same input report. There are a lot of devices that are needing
the quirk HID_MULTI_INPUT but this quirk doesn't match the actual HID
description as it is based on the report ID.
Given that most devices with MULTI_INPUT I can think of split nicely
the devices inputs into application, it is a good thing to split the
devices by default based on this assumption.
Also make hid-multitouch following this rule, to not have to deal
with too many input created.
While we are at it, fix some checkpatch complaints about converting
'unsigned' to 'unsigned int'.

This series from Benjamin Tissoires finally removes one of the big PITAs
in the hid-core, which is the absolute need of having added all the new
device IDs into the horrid hid_have_special_driver[]
Given all the effort distros have done with splash-screens to give
users a nice clean boot experience, we really want dmesg --level=err
to not print anything unless there is a real problem with either the
hardware or the kernel. Buggy HID descriptors unfortunately happen
all too often, so lower the log level to warning keep the console
clear of error messages such as:

Most HID devices behave properly when they are used with hid-generic.
Since kernel v4.12, we do not poll for input reports at plug in, so
hid-generic should behave properly with all HID devices.
There has been a long standing list of HID devices that have a special
driver. It used to be just a few, but with time, this list went too big,
and we can not ask users to know which HID special driver will pick up
their device.
We can teach hid-generic to be nice with others. If a device is not
explicitly marked with HID_QUIRK_HAVE_SPECIAL_DRIVER, we can allow
hid-generic to pick up the device as long as no other loaded HID driver
will match the device.
When the special driver appears, hid-generic can step back and let
the special driver handling the device. In case this special driver
is removed, this good old pal of hid-generic will rebind to the device.
This basically makes the list hid_have_special_driver[] useless. It
still allows to not see a hid-generic driver bound and removed during
boot, so we can keep it around.
This will also help other people to have a special HID driver without
the need of recompiling hid-core.

Better having all the devices quirks in one place.
Note that this change introduces an initial lookup for the device in
hid_gets_squirk(), which should not theoretically be required, but which
actually allows to not have to reparse the list of ignored devices
if we call hid_lookup_quirks twice.

It is better to centralize the information of special devices in one
single file. Instead of manually parsing the list of devices that
have a special driver or those that need to be ignored, introduce
HID_QUIRK_HAVE_SPECIAL_DRIVER and set the correct quirks while fetching
those quirks.

This driver does 2 things:
- Apply the MULTI_INPUT quirk to create separate joypad device nodes
for each one of the 4 connectors.
- Rename the input devices so that their names are different, and allow
users to recognise which device corresponds to which physical port,
including the SNES (Mario Paint) Mouse.

There are many situations where generic HID driver provides some basic level
of support for certain device, but later this support (usually by implementing
vendor-specific extensions of HID protocol) is extended and the support moved
over to a separate (usually per-vendor) specific driver.
This might bring a rather unpleasant suprise for users, as all of a sudden
there is a new config option they have to enable in order to get any support
for their device whatsoever, although previous kernel versions provided basic
support through the generic driver. Which is rightfully seen as a regression.
Fix this by including the entry for a particular device in
hid_have_special_driver[] iff the specific config option has been specified,
and let generic driver handle the device otherwise.
Also make the behavior of hid_scan_report() (where the same decision is being
taken on a per-report level) consistent.
While at it, reshuffle the hid_have_special_driver[] a bit to restore the
alphabetical ordering (first order by config option, and within those
sections order by VID).
This is considered a short-term solution, before generic way of giving
precedence to special drivers and falling back to generic driver is
figured out.
While at it, fixup a missing entry for GFRM driver; thanks to Hans de Geode for
spotting this (and for discovering a few issues in the conversion).

The HID transport drivers either re-implement exactly the same logic
(usbhid, i2c-hid) or forget to implement it (usbhid) which causes issues
when the same device is accessed via multiple interfaces (for example input
device through evdev and also hidraw). Let's muve the locking logic into
HID core to make sure the serialized behavior is always enforced.
Also let's uninline and move hid_hw_start() and hid_hw_stop() into hid-core
as hid_hw_start() is somewhat large and do not believe we get any benefit
from these two being inline.

The ITE8595 keyboard uses the HID_GD_RFKILL_BTN usage code
from the Wireless Radio Controls Application Collection Microsoft
has defined for Windows 8 and later.
However it has a quirk, when the rfkill hotkey is pressed it does
generate a report for the collection, but the reported value is
always 0. Luckily it is the only button in this collection / report,
and it sends a report on release only, so receiving a report means the
button was pressed.
This commit adds a hid-ite driver which watches for the Wireless Radio
Controls Application Collection report and then reports a KEY_RFKILL event,
ignoring the value, making the rfkill on this keyboard work.
