Patch just rearranges lines to be more compact and/or readable. Additionally it
converts double space to one in several places.
There is no functional change.

A HID device could send a malicious feature report that would cause the
sensor-hub HID driver to read past the end of heap allocation, leaking
kernel memory contents to the caller.

This removes most of the dependencies between hid drivers and usbhid.
The patch was constructed by replacing all occurences of
usbhid_wait_io() by its hid_hw_wait() counterpart.
Then, drivers not requiring USB_HID anymore have their USB_HID
dependency cleaned in the Kconfig file.
As of today, few drivers are still requiring an explicit USB layer
dependency:
* ntrig (a patch is on its way)
* multitouch (one patch following and another on its way)
* lenovo tpkbd
* roccat
* sony
The last three are two deeply using direct calls to the usb subsystem
to be able to be cleaned right now.

This allows the hid drivers to be independent from the transport layer.
The patch was constructed by replacing all occurences of
usbhid_submit_report() by its hid_hw_request() counterpart.
Then, drivers not requiring USB_HID anymore have their USB_HID
dependency cleaned in the Kconfig file.
Finally, few drivers still depends on USB_HID. Many of them
are requiring the io wait callback. They are found in the next patch.

We now have two transport mediums: USB and I2C, where sensor hubs can
exists. So instead of constraining the driver to only these two we let it
to match any HID bus as long as the group is HID_GROUP_SENSOR_HUB.

Use the new module_hid_driver macro in all HID drivers that have
a simple register/unregister init/exit.
This also converts the hid drivers that test for a failure of
hid_register_driver() and report the failure. Using module_hid_driver
in those drivers removes the failure message.

It should not be necessary to add IDs for HID sensor hubs to lists in
hid-core.c and hid-sensor-hub.c. So instead of a whitelist, autodetect such USB
HID sensor hubs, based on a collection of type physical inside a useage page of
type sensor. If some sensor hubs stil must be usable as raw devices, a
blacklist might be created.

Fix below issues:
1. In the case of goto err_close, hid_hw_stop(hdev) is called twice. Fix it.
2. If fails to allocate MFD device name, we also need to free all
successfully allocated names in previous iterations.
3. In sensor_hub_remove(), Call hid_hw_close() before hid_hw_stop().
4. Adjust unnecessary change lines for hid_err.

Current implementation of hid_hw_start() allows connect_mask to be 0.
Setting hdev->claimed = HID_CLAIMED_INPUT before calling hid_hw_start()
is not necessary. Remove it.

Adding processing for HID Sensor usage table as defined by
HID 1.12, Request #: HUTRR39, dated 05 May, 2011.
This driver uses HID driver framework to register, send and
receive events.
This uses MFD framework, so that actual processing for a
specific usage id can be done in a different driver. For
example an accelerometer driver can be a separate driver and
use the interface provided by this driver to register for
events.
