7ceeff443b Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
Pull HID fixes from Jiri Kosina:

 - fix a small bug in computation of report size, which might cause some
   devices (Atmel touchpad found on the Samsung Ativ 9) to reject
   reports with otherwise valid contents

 - a few device-ID specific quirks/additions piggy-backing on top of it

825747bb85 HID: sensor-hub: Add in quirk for sensor hub in Lenovo Ideapad Yogas
The sensor hub in Lenovo Yogas needs the enumeration quirk.  I've been running
the patch for over a month with no problems, whereas the unpatched drivers
reliably mis-initialized the sensors.

2f433083e8 HID: add NO_INIT_REPORTS quirk for Synaptics Touch Pad V 103S
This touchpad seriously dislikes init reports, not only timeing out, but
also refusing to work after this.

19e4ec525b HID: core: fix computation of the report size
The extra seven bits are only required when allocating the report buffer.
We can not use those extra bytes for the length of the report in the
generic implementation of .request because the device might (will) refuse
the set_report command.
This has been verified on the Atmel touchpad found on the Samsung Ativ 9
plus, which uses hid-multitouch and HID over I2C. Without this fix, the
device refuses to switch to the multitouch mode, and it becomes unresponsive
from the user point of view.

Actually, this has been discussed during the initial submission of the
commit 4fa5a7f76c, see
https://patchwork.kernel.org/patch/3621751/

Unfortunately, I completely forgot about it later.

e24d0d399b HID: core: do not scan constant input report
The Microsoft Surface Type/Touch Cover 2 is a fancy device which advertised
itself as a multitouch device but with constant input reports.
This way, hid_scan_report() gives the group MULTITOUCH to it, but
hid-multitouch can not handle it due to the constant collection ignored
by hid-input.

To prevent such crap in the future, and while we do not fix this particular
device, make the scan_report coherent with hid-input.c, and ignore constant
input reports.

f3b0cbce01 Revert "HID: microsoft: Add ID's for Surface Type/Touch Cover 2"
This reverts commit 117309c51d.

The MS Surface Pro 2 has an USB composite device with 3 interfaces
- interface 0 - sensor hub
- interface 1 - wacom digitizer
- interface 2 - the keyboard cover, if one is attached
This USB composite device changes it product id dependent on if and which
keyboard cover is attached. Adding the covers to hid_have_special_driver
prevents loading the right hid drivers for the other two interfaces, all 3
get loaded with hid-microsoft. We don't even need hid-microsoft for the
keyboards. We have to revert this to load the right hid modules for each
interface.

     Remote Controller
   - add API for SDR devices.  Drivers are still on staging
   - some API improvements for getting EDID data from media
     inputs/outputs
   - new DVB frontend driver for drx-j (ATSC)
   - one driver (it913x/it9137) got removed, in favor of an improvement
     on another driver (af9035)
   - added a skeleton V4L2 PCI driver at documentation
   - added a dual flash driver (lm3646)
   - added a new IR driver (img-ir)
   - added an IR scancode decoder for the Sharp protocol
   - some improvements at the usbtv driver, to allow its core to be
     reused.
   - added a new SDR driver (rtl2832u_sdr)
   - added a new tuner driver (msi001)
   - several improvements at em28xx driver to fix PM support, device
     removal and to split the V4L2 specific bits into a separate
     sub-driver
   - one driver got converted to videobuf2 (s2255drv)
   - the e4000 tuner driver now follows an improved binding model
   - some fixes at V4L2 compat32 code
   - several fixes and enhancements at videobuf2 code
   - some cleanups at V4L2 API documentation
   - usual driver enhancements, new board additions and misc fixups"

[ NOTE! This merge effective drops commit 4329b93b28 ("of: Reduce
  indentation in of_graph_get_next_endpoint").

  The of_graph_get_next_endpoint() function was moved and renamed by
  commit fd9fdb78a9 ("[media] of: move graph helpers from
  drivers/media/v4l2-core to drivers/of").  It was originally called
  v4l2_of_get_next_endpoint() and lived in the file
  drivers/media/v4l2-core/v4l2-of.c.

  In that original location, it was then fixed to support empty port
  nodes by commit b9db140c1e ("[media] v4l: of: Support empty port
  nodes"), and that commit clashes badly with the dropped "Reduce
  intendation" commit.  I had to choose one or the other, and decided
  that the "Support empty port nodes" commit was more important ]

30f58877bf HID: sensor-hub: add sensor hub quirk for ThinkPad Helix
Just like some of the other laptops/tablets on the market with ultrabook
sensors, the ThinkPad Helix's sensor hub requires a special quirk in
order for it to power on properly. Without it the sensors are detected
by the kernel and set up as usual, but they won't output any data. This
will also fix the sensors on any other laptops with the same model of
sensor hub.

4522643aa9 HID: uhid: Add UHID_CREATE2 + UHID_INPUT2
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.

6fd182028c HID: remove hid_output_raw_report transport implementations
Nobody calls hid_output_raw_report anymore, and nobody should.
We can now remove the various implementation in the different
transport drivers and the declarations.

e534a93522 HID: sony: do not rely on hid_output_raw_report
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 3a75b24949
(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.

  hid_output_raw_report(hdev, buf, sizeof(buf), HID_FEATURE_REPORT);
is strictly equivalent to:

Then replace buf[0] by the appropriate define.

So use the new api.

5fdb83f190 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.

0fa9c61618 HID: multitouch: remove registered devices with default behavior
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.

d2d782fcce HID: sony: Prevent duplicate controller connections.
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.
