By allowing the drivers to return a "const *" they can constify their

This makes it clear to driver authors that the HID core will not modify
those reports and they can be reused for multiple devices.
Furthermore security is slightly improved as those reports are protected
against accidental or malicious modifications.

HID: magicmouse: prevent division by 0 on scroll

In hid_magicmouse, if the user has set scroll_speed to a value between
55 and 63 and scrolls seven times in quick succession, the
step_hr variable in the magicmouse_emit_touch function becomes 0.

That causes a division by zero further down in the function when
it does `step_x_hr /= step_hr`.

To reproduce, create `/etc/modprobe.d/hid_magicmouse.conf` with the
following content:

```
options hid_magicmouse scroll_acceleration=1 scroll_speed=55
```

Then reboot, connect a Magic Mouse and scroll seven times quickly.
The system will freeze for a minute, and after that `dmesg` will
confirm that a division by zero occurred.

Enforce a minimum of 1 for the variable so the high resolution
step count can never reach 0 even at maximum scroll acceleration.

HID: magicmouse: enable high-resolution scroll

The Magic Mouse, generations 1 and 2, doesn't have a physical scroll
wheel, instead, the REL_WHEEL and REL_HWHEEL events are emulated
when sliding a finger on the surface of the mouse.
However, the smooth movement of the finger is transformed into a step
based scroll on the screen, leading to a suboptimal user experience.

Emulate high-resolution scroll by sending REL_WHEEL_HI_RES and
REL_HWHEEL_HI_RES events so the scroll on the screen is closer to the
finger movement.

HID: magicmouse: fix 3 button emulation of Mouse 2

It is observed that, with 3 button emulation, when middle button is
clicked, either the left button or right button is clicked as well. It
is caused by hidinput "correctly" acting on the event, oblivious to the
3 button emulation.

As raw_event has taken care of everything, no further processing is
needed. However, the only way to stop at raw_event is to return an error
(negative) value. Therefore, the processing is stopped at event instead.

HID: generic: create one input report per application type

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'.
