The Sixaxis and DualShock 4 want HID output reports sent on the control
endpoint when connected via Bluetooth. Set the
HID_QUIRK_NO_OUTPUT_REPORTS_ON_INTR_EP flag for these devices so hidraw write()
works properly.

UHID_CREATE2:
HID report descriptor data (rd_data) is an array in struct uhid_create2_req,
instead of a pointer. Enables use from languages that don't support pointers,
e.g. Python.
UHID_INPUT2:
Data array is the last field of struct uhid_input2_req. Enables userspace to
write only the required bytes to kernel (ev.type + ev.u.input2.size + the part
of the data array that matters), instead of the entire struct uhid_input2_req.
Note:
UHID_CREATE2 increases the total size of struct uhid_event slightly, thus
increasing the size of messages that are queued for userspace. However, this
won't affect the userspace processing of these events.

Fix issue with the sleeping calling hid_hw_request under spinlock.
When i2c is used as HID transport, this is calling kmalloc, which
can sleep. So remove call to this function while under spinlock.

hid_out_raw_report is going to be obsoleted as it is not part of the
unified HID low level transport documentation
(Documentation/hid/hid-transport.txt)
To do so, we need to introduce two new quirks:
* HID_QUIRK_NO_OUTPUT_REPORTS_ON_INTR_EP: this quirks prevents the
transport driver to use the interrupt channel to send output report
(and thus force to use HID_REQ_SET_REPORT command)
* HID_QUIRK_SKIP_OUTPUT_REPORT_ID: this one forces usbhid to not
include the report ID in the buffer it sends to the device through
HID_REQ_SET_REPORT in case of an output report
This also fixes a regression introduced in commit 3a75b24949a8
(HID: hidraw: replace hid_output_raw_report() calls by appropriates ones).
The hidraw API was not able to communicate with the PS3 SixAxis
controllers in USB mode.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Updates for v3.15
Quite a busy release for ASoC this time, more on janitorial work than
exciting new features but welcome nontheless:
- Lots of cleanups from Takashi for enumerations; the original API for
these was error prone so he's refactored lots of code to use more
modern APIs which avoid issues.
- Elimination of the ASoC level wrappers for I2C and SPI moving us
closer to converting to regmap completely and avoiding some
randconfig hassle.
- Provide both manually and transparently locked DAPM APIs rather than
a mix of the two fixing some concurrency issues.
- Start converting CODEC drivers to use separate bus interface drivers
rather than having them all in one file helping avoid dependency
issues.
- DPCM support for Intel Haswell and Bay Trail platforms.
- Lots of work on improvements for simple-card, DaVinci and the Renesas
rcar drivers.
- New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
CSR SiRF SoC.

The default multitouch protocol class in use since the kernel v3.9 is
working quite well. Since its inclusion, the only devices we had to tweak
were those who really need quirks (GeneralTouch, FocalTech and Wistron,
the 3 of them are Win 7 certified ones).
The flow of new unhandled devices has stopped, which is great and I think
it's time to reduce the list of registered device.
This commit removes only the registration in the kernel of devices that
use the class MT_CLS_DEFAULT, or that can use it. By that, I mean that I
checked all the recordings I have, and the produced input device and
events are the same before and after applying the patch.
This gives two benefits:
- remove a bunch of lines of codes
- prevent bad handling of existing registered devices which are using a
different protocol while using the same VID/PID (I got the case of a
Quanta 3008 recently).
I also removed the associated classes (MT_CLS*). I kept their #define in
case people use the new_id sysfs node with a non standard class (their
should be really few people now, but we never now). This is why there
are /* reserved .... */.
Last, I add a comment on top of mt_devices[] definition to remember people
(and myself) not to include devices for the beauty of it.
To people still trying to add devices with the default class:
"""
Guys, try out your device under a kernel greater or equal to v3.9. If it
works, you are all set. Adding your VID/PID to the kernel only brings us
overload and you won't get anything from it _because_ even a backport of
this shiny patch will _not_ make the device work under 3.0, 3.2, 3.4 or
even 3.8.
So if it works, it works.
If it does not work, then yes, submit a patch or call for help.
In any cases, if you want me to do regression tests, I'd be happy to
get some traces of your device. But I won't patch the kernel if it works.

During device removal hid_disconnect() is called via hid_hw_stop() to
stop the device and free all its resources, including the sysfs
files. The problem is that if a user space process, such as upowerd,
holds a reference to a hidraw file the corresponding sysfs files will
be kept around (drop_ref() does not call device_destroy() if the open
counter is not 0) and it will be usb_disconnect() who, by calling
device_del() for the USB device, will indirectly remove the sysfs
files of the hidraw device (sysfs_remove_dir() is recursive these
days). Because of this, by the time user space releases the last
reference to the hidraw file and drop_ref() tries to destroy the
device the sysfs files are already gone and the kernel will print
the warning above.
Fix this by calling device_destroy() at USB disconnect time.

If a Sixaxis or Dualshock 4 controller is connected via USB while already
connected via Bluetooth it will cause duplicate devices to be added to the
input device list.
To prevent this a global list of controllers and their MAC addresses is
maintained and new controllers are checked against this list. If a duplicate
is found, the probe function will exit with -EEXIST.
On USB the MAC is retrieved via a feature report. On Bluetooth neither
controller reports the MAC address in a feature report so the MAC is parsed from
the uniq string. As uniq cannot be guaranteed to be a MAC address in every case
(uHID or the behavior of HIDP changing) a parsing failure will not prevent the
connection.

In HID sensor hub, HID physical ids are used to represent different sensors.
For example physical id of 0x73 in usage page = 0x20, represents an
accelerometer. The HID sensor hub driver uses this physical ids to create
platform devices using MFD. There is 1:1 correspondence between an phy id and a
client driver.
But in some cases these physical ids are reused. There is a phy id 0xe1, which
specifies a custom sensor, which can exist multiple times to represent various
custom sensors. In this case there can be multiple instances of client MFD
drivers, processing specific custom sensor. In this case when client driver
looks for report id or a field index, it should still get the report id
specific to its own type. This is also true for reports, they should be
directed towards correct instance. This change introduce a way to parse and
tie physical devices to their correct instance.
Summary of changes:
- To get physical ids, use collections. If a collection of type=physical
exist then use usage id as in the name of platform device name
- As part of the platform data, we assign a hdsev instance, which has
start and end of collection indexes. Using these indexes attributes
can be tied to correct MFD client instances
- When a report is received, call callback with correct hsdev instance.
In this way using its private data stored as part of its registry, it
can distinguish different sensors even when they have same physical and
logical ids.
