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.

report cannot be NULL, fortunately as we use it before we check !

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.

Dan Carpenter 24db0d75d3 HID: sensors: remove some unneeded checks
"report_id" is unsigned so it's never less than zero.  These checks can
be removed without any problem.

Dan Carpenter 2b7c4b8e3e HID: sensors: use GFP_ATOMIC under spinlock
We're holding a spinlock here so we can't call kmalloc() with
GFP_KERNEL.

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.
