2013-09-04HID: hid-sensor-hub: fix indentation accross the codeAndy Shevchenko
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.

2013-02-25HID: use hid_hw_wait() instead of direct call to usbhidBenjamin Tissoires
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.

2013-02-25HID: use hid_hw_request() instead of direct call to usbhidBenjamin Tissoires
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.

2013-02-18HID: sensor-hub: don't limit the driver only to USB busMika Westerberg
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.

2013-01-03HID: Use module_hid_driver macroH Hartley Sweeten
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.

2012-12-12HID: sensors: autodetect USB HID sensor hubsAlexander Holler
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.

2012-09-22HID: hid-sensor-hub: Fix sensor_hub_probe error handlingAxel Lin
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.

2012-09-06HID: sensors: introduce sensor frameworksrinivas pandruvada
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.
