commit 403cfb53fb450d53751fdc7ee0cd6652419612cf upstream.
Some systems although they have firmware class 'M', which usually
needs a work around to not crash, must not be subjected to the
work around because the work around crashes them. They cannot be
told apart by their own device descriptor, but as they are part
of compound devices, can be identified by looking at their siblings.

commit d4b1bba76171cb783e32441b28462fe841073ed8 upstream.
Most of the hid sensor field size is reported in report_size field
in the report descriptor. For rotation fusion sensor the quaternion
data is 16 byte field, the report size was set to 4 and report
count field is set to 4. So the total size is 16 bytes. But the current
driver has a bug and not taking account for report count field. This
causes user space to see only 4 bytes of data sent via IIO interface.
The number of bytes in a field needs to take account of report_count
field. Need to multiply report_size and report_count to get total
number of bytes.

commit 95d50b6c5e18ff7351c5f2a6ff53afaed5f7e664 upstream.
Certain devices with class HID, protocol None did not work with the HID
driver at one point, and as a result were bound to usbtouchscreen
instead as of commit 139ebe8 ("Input: usbtouchscreen - fix eGalax HID
ignoring"). This change was prompted by the following report:
https://lkml.org/lkml/2009/1/25/127
Unfortunately, the device mentioned in this report is no longer
available for testing.
We've recently discovered that some devices with class HID, protocol
None do not work with usbtouchscreen, but do work with usbhid. Here is
the report that made this evident:
http://comments.gmane.org/gmane.linux.kernel.input/31710
Driver binding for these devices has flip-flopped a few times, so both
of the above reports were regressions.
This situation would appear to leave us with no easy way to bind every
device to the right driver. However, in my own testing with several
devices I have not found a device with class HID that does not work with
the current HID driver. It is my belief that changes to the HID driver
since the original report have likely fixed the issue(s) that made it
unsuitable at the time, and that we should prefer it over usbtouchscreen
for these devices. In particular, HID quirks affecting these devices
were added/removed in the following commits since then:
fe6065d HID: add multi-input quirk for eGalax Touchcontroller
77933c3 Merge branch 'egalax' into for-linus
ebd11fe HID: Add quirk for eGalax touch controler.
d34c4aa HID: add no-get quirk for eGalax touch controller
This patch makes the HID driver no longer ignore eGalax/D-Wav/EETI
devices with class HID. If there are in fact devices with class HID
that still do not work with the HID driver, we will see another round of
regressions. In that case I propose we investigate why the device is
not working with the HID driver rather than re-introduce regressions for
functioning HID devices by again binding them to usbtouchscreen.
The corresponding change to usbtouchscreen will be made separately.

commit 80897aa787ecd58eabb29deab7cbec9249c9b7e6 upstream.
UHID allows short writes so user-space can omit unused fields. We
automatically set them to 0 in the kernel. However, the 64/32 bit
compat-handler didn't do that in the UHID_CREATE fallback. This will
reveal random kernel heap data (of random size, even) to user-space.

Revert some changes done in 774638386826621c984ab6994439f474709cac5e.
Revert all changes done in hidinput_calc_abs_res as it mistakingly used
"Unit" item exponent nibbles to affect resolution value. This wasn't
breaking resolution calculation of relevant axes of any existing
devices, though, as they have only one dimension to their units and thus
1 in the corresponding nible.
Revert to reading "Unit Exponent" item value as a signed integer in
hid_parser_global to fix reading specification-complying values. This
fixes resolution calculation of devices complying to the HID standard,
including Huion, KYE, Waltop and UC-Logic graphics tablets which have
their report descriptors fixed by the drivers.
Explanations follow.
There are two "unit exponents" in HID specification and it is important
not to mix them. One is the global "Unit Exponent" item and another is
nibble values in the global "Unit" item. See 6.2.2.7 Global Items.
The "Unit Exponent" value is just a signed integer and is used to scale
the integer resolution unit values, so fractions can be expressed.
The nibbles of "Unit" value are used to select the unit system (nibble
0), and presence of a particular basic unit type in the unit formula and
its *exponent* (or power, nibbles 1-6). And yes, the latter is in two
complement and zero means absence of the unit type.
Taking the representation example of (integer) joules from the
specification:
[mass(grams)][length(centimeters)^2][time(seconds)^-2] * 10^-7
the "Unit Exponent" would be -7 (or 0xF9, if stored as a byte) and the
"Unit" value would be 0xE121, signifying:
Nibble Part Value Meaning
----- ---- ----- -------
0 System 1 SI Linear
1 Length 2 Centimeters^2
2 Mass 1 Grams
3 Time -2 Seconds^-2
To give the resolution in e.g. hundredth of joules the "Unit Exponent"
item value should have been -9.
See also the examples of "Unit" values for some common units in the same
chapter.
However, there is a common misunderstanding about the "Unit Exponent"
value encoding, where it is assumed to be stored the same as nibbles in
"Unit" item. This is most likely due to the specification being a bit
vague and overloading the term "unit exponent". This also was and still
is proliferated by the official "HID Descriptor Tool", which makes this
mistake and stores "Unit Exponent" as such. This format is also
mentioned in books such as "USB Complete" and in Microsoft's hardware
design guides.
As a result many devices currently on the market use this encoding and
so the driver should support them.

The input core has an internal spinlock that is acquired during event
injection via input_event() and friends but also held during FF callbacks.
That means, there is no way to share a lock between event-injection and FF
handling. Unfortunately, this is what is required for wiimote state
tracking and what we do with state.lock and input->lock.
This deadlock can be triggered when using continuous data reporting and FF
on a wiimote device at the same time. I takes me at least 30m of
stress-testing to trigger it but users reported considerably shorter
times (http://bpaste.net/show/132504/) when using some gaming-console
emulators.
The real problem is that we have two copies of internal state, one in the
wiimote objects and the other in the input device. As the input-lock is
not supposed to be accessed from outside of input-core, we have no other
chance than offloading FF handling into a worker. This actually works
pretty nice and also allows to implictly merge fast rumble changes into a
single request.
Due to the 3-layered workers (rumble+queue+l2cap) this might reduce FF
responsiveness. Initial tests were fine so lets fix the race first and if
it turns out to be too slow we can always handle FF out-of-band and skip
the queue-worker.

udev has this nice feature of creating "dead" /dev/<node> device-nodes if
it finds a devnode:<node> modalias. Once the node is accessed, the kernel
automatically loads the module that provides the node. However, this
requires udev to know the major:minor code to use for the node. This
feature was introduced by:
commit 578454ff7eab61d13a26b568f99a89a2c9edc881

driver core: add devname module aliases to allow module on-demand auto-loading
However, uhid uses dynamic minor numbers so this doesn't actually work. We
need to load uhid to know which minor it's going to use.
Hence, allocate a static minor (just like uinput does) and we're good
to go.

The zeroplus HID driver was not checking the size of allocated values
in fields it used. A HID device could send a malicious output report
that would cause the driver to write beyond the output report allocation
during initialization, causing a heap overflow:

Many drivers need to validate the characteristics of their HID report
during initialization to avoid misusing the reports. This adds a common
helper to perform validation of the report exisitng, the field existing,
and the expected number of values within the field.

After the last architecture switched to generic hard irqs the config
options HAVE_GENERIC_HARDIRQS & GENERIC_HARDIRQS and the related code
for !CONFIG_GENERIC_HARDIRQS can be removed.

This reverts commits 61e00655e9cb, 73f8645db191 and 8e22ecb603c8:
"Input: introduce BTN/ABS bits for drums and guitars"
"HID: wiimote: add support for Guitar-Hero drums"
"HID: wiimote: add support for Guitar-Hero guitars"
The extra new ABS_xx values resulted in ABS_MAX no longer being a
power-of-two, which broke the comparison logic. It also caused the
ioctl numbers to overflow into the next byte, causing problems for that.
We'll try again for 3.13.

Patch just rearranges lines to be more compact and/or readable. Additionally it
converts double space to one in several places.
