Mika Westerberg 0d1e4b024f HID: sensor-hub: don't limit the driver only to USB bus
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.

H Hartley Sweeten f425458eaf HID: Use module_hid_driver macro
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.

Alexander Holler 83499b52c6 HID: sensors: autodetect USB HID sensor hubs
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.

Axel Lin f2f13a68c3 HID: hid-sensor-hub: Fix sensor_hub_probe error handling
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.

Axel Lin 3f257caf2d HID: hid-sensor-hub: Remove hdev->claimed setting
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.

"report_id" is unsigned so it's never less than zero.  These checks can

srinivas pandruvada 401ca24fb3 HID: sensors: introduce sensor framework
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.
