edd2126aa8 HID: wacom: make sysfs permissions more strict
It's not really dangerous in this driver, but it's against general
practice and worth fixing.

Wacom uses the attribute for changing the reporting speed of the
tablet (and this actually requires poking the device in the
background) (still I wouldn't consider it a security issue though).

udev is a proper place to handle this.

04561c5aa2 HID: Add Force Feedback support for EMS Trio Linker Plus II
The device has connections for GameCube, PlayStation 2 and Dreamcast
controllers, however Force Feedback is only supported for PS2 and GC
controllers.

When using a PS2 controller it may be necessary to press the "Analog" button to
enable support for both motors (this behavior is identical to the Windows
driver, I have found no way to avoid that).

In that window, the device may be unplugged and removed form the

Override usbhid_output_raw_report in order to force output reports (sent

The Sony Sixaxis (PS3 Controller) accepts output reports only on the
control endpoint, it silently discards them when they arrive over the
interrupt endpoint where usbhid would normally deliver them.

6038f373a3 llseek: automatically add .llseek fop
All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.

The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.

New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time.  Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.

The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.

Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.

Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.

   (hid-egalax.c), the MULTI_INPUT quirk is also applied, preventing
   the hid-egalax driver from working. This patch removes the quirk
   so the hid-egalax driver can handle the device correctly.
2) The x and y coordinates sent by the screen in multi-touch mode are
   shifted by three bits from the events sent in single-touch mode, thus
   the coordinates are out of range, leading to the pointer being stuck
   in the bottom-right corner if no additional calibration is applied
   (e.g. in the X evdev driver). This patch shifts the coordinates back.
   This does not decrease accuracy as the last three bits of the "wrong"
   coordinates are always 0.
3) Only multi-touch pressure events are sent, single touch emulation is
   missing pressure information. This patch adds single-touch
   ABS_PRESSURE events.

fe2c91ee24 HID: don't Send Feature Reports on Interrupt Endpoint
Feature reports should only be sent on the control endpoint.

The USB HID standard is unclear and confusing on this issue. It seems to
suggest that Feature reports can be sent on a HID device's Interrupt OUT
endpoint.  This cannot be the case because the report type is not encoded in
transfers sent out the Interrput OUT endpoint.  If Feature reports were sent on
the Interrupt OUT endpint, they would be indistinguishable from Output reports
in the case where Report IDs were not used.

Further, Windows and Mac OS X do not send Feature reports out the interrupt OUT
Endpoint.  They will only go out the Control Endpoint.

In addition, many devices simply do not hande Feature reports sent out the
Interrupt OUT endpoint.

My macbook infrared remote control was broken by commit

This device appears in dmesg as:

It stopped working as lircd was getting ENODEV when opening /dev/usb/hiddev0.

AFAICS hiddev_driver is a dummy driver so usb_find_interface(&hiddev_driver)
does not find anything.

The device is associated with the usbhid driver, so let's do
usb_find_interface(&hid_driver) instead.

a462230e16 HID: magicmouse: enable Magic Trackpad support
The trackpad speaks a similar, but different, protocol from the magic
mouse. However, only small code tweaks here and there are needed to make
basic multitouch work.

Extra logic is required for single-touch emulation of the touchpad. The
changes made here take the approach that only one finger may emulate the
single pointer when multiple fingers have touched the screen. Once that
finger is raised, all touches must be raised before any further single
touch events can be sent.

Sometimes the magic trackpad sends two distinct touch reports as one big
report. Simply splitting the packet in two and resending them through
magicmouse_raw_event ensures they are handled properly.

I also added myself to the copyright statement.

67168fd7d4 HID: rdesc parser: remove local item size limit
The HID report descriptor parser requires local items, except "delimiters",
to have data. I.e. to have non-zero size. This removes the restriction.

The HID specification doesn't seem to have such restriction and, for
example, a "usage" item could have zero size if the usage ID is zero.
At least one usage page - Keyboard/Keypad lists zero ID as valid.

This doesn't seem to happen in the wild, probably because the official tool
for authoring report descriptors always puts data even for zero values for
some items, including "usage" items.

However, this makes little sense and at least one open source tool for
descriptor authoring generates zero data size "usage" items, which saves
some space, especially if many such items are used in a descriptor.

72a4634486 HID: add support for two Waltop tablets
Add support for Waltop Slim Tablet 5.8 inch and Media Tablet 10.6 inch.

These (and other Waltop) tablets are usually sold by different companies
(such as Genius and Trust) and with different names, but with the same USB
vendor/product IDs.

Slim Tablet 5.8 inch is known to also be sold as Genius G-Pen F350 and Trust
Widescreen Mini Tablet (item no 16485).

Media Tablet 10.6 inch is known to also be sold as Genius G-Pen M609 and
M609X. Of these only the latter is known to be supported.

83e4491818 USB HID: Add ID for eGalax Multitouch used in JooJoo tablet
The JooJoo tablet (http://thejoojoo.com/) contains an "eGalax Inc. USB
TouchController", and this patch hooks it up to the egalax-touch driver.
Without the patch we don't get any cursor motion, since it comes through
Z/RX rather than X/Y.

(The egalax-touch driver does not yet generate a correct event sequence
for the "serial" protocol used by this device, though -- see the note
added to the code, which comes from research by Stéphane Chatty.)

9c9e54a8df HID: hiddev: fix memory corruption due to invalid intfdata
Commit bd25f4dd69 ("HID: hiddev: use usb_find_interface,
get rid of BKL") introduced using of private intfdata in hiddev for
purpose of storing hiddev pointer.

This is a problem, because intf pointer is already being set to struct
hid_device pointer by HID core. This obviously lead to memory corruptions
at device disconnect time, such as

WARNING: at lib/kobject.c:595 kobject_put+0x37/0x4b()
kobject: '(null)' (ffff88011e9cd898): is not initialized, yet kobject_put() is being called.

Convert hiddev into accessing hiddev through struct hid_device which is
in intfdata already.

7032269e87 HID: hiddev: protect against disconnect/NULL-dereference race
One of our users reports consistently hitting a NULL dereference that
resolves to the "hid_to_usb_dev(hid);" call in hiddev_ioctl(), when
disconnecting a Lego WeDo USB HID device from an OLPC XO running
Scratch software.  There's a FIXME comment and a guard against the
dereference, but that happens farther down the function than the
initial dereference does.

This patch moves the call to be below the guard, and the user reports
that it fixes the problem for him.  OLPC bug report:

f8a489cc5f HID: Add support for UC-Logic WP????U tablets
Add support for UC-Logic WP4030U, WP5540U and WP8060U tablets.
These tablets are usually sold by Genius, Trust and possibly others under
different names and in different cases, but with the original USB
vendor/product IDs.

Currently, these tablets are supported by standalone X.org driver WizardPen.
This patch aims to fix them in the kernel and make them supported by the
generic evdev X.org driver. Still, some minor fixes in the X.org driver are
to be made for the full stack support.

50b6369767 HID: Add Tablet Pick -> BTN_STYLUS2 mapping
Many tablet input drivers use BTN_STYLUS2 code to report a second
tablet stylus button. Yet, the generic HID input driver doesn't map it.
Apparently, because there is no corresponding usage in the HID Usage Tables.

This patch selects a compromise usage - "Tablet Pick" (0x46) to be mapped to
BTN_STYLUS2. Some tablets use "Eraser" usage, but mapping it to a button
wouldn't be entirely correct, because the specification says it may be "a
pressure quantity".

73e4008ddd HID: allow resizing and replacing report descriptors
Update hid_driver's report_fixup prototype to allow changing report

Update existing usage accordingly.

This is to give more freedom in descriptor fixup and to allow having a whole
