With the headersize check outside of the loop, the second time through
the loop the: "payload_len = recv_msg->hdr.size;" statement may deref
recv_msg while it is pointing outside of our input buffer.
Move the headersize check to inside the loop to fix this.

The IBM/Lenovo Scrollpoint mice feature a trackpoint-like stick instead of a
scrolling wheel capable of 2-D (vertical+horizontal) scrolling. hid-generic
does only expose 1-D (vertical) scrolling functionality for these mice. This
patch adds support for horizontal scrolling for the IBM/Lenovo Scrollpoint mice
to hid-lenovo.

This is something that bothered us from a long time. When hid-input
doesn't know how to map a usage, it uses *_MISC. But there is something
else which increments the usage if the evdev code is already used.
This leads to few issues:
- some devices may have their ABS_X mapped to ABS_Y if they export a bad
set of usages (see the DragonRise joysticks IIRC -> fixed in a specific
HID driver)
- *_MISC + N might (will) conflict with other defined axes (my Logitech
H800 exports some multitouch axes because of that)
- this prevents to freely add some new evdev usages, because "hey, my
headset will now report ABS_COFFEE, and it's not coffee capable".
So let's try to kill this nonsense, and hope we won't break too many
devices.
I my headset case, the ABS_MISC axes are created because of some
proprietary usages, so we might not break that many devices.
For backward compatibility, a quirk HID_QUIRK_INCREMENT_USAGE_ON_DUPLICATE
is created and can be applied to any device that needs this behavior.

The CHPN0001 ACPI device has a _CID of PNP0C50 and even has the _DSM to
get the HID descriptor address, but it is not a HID device at all.
It uses its own protocol which is handled by the (still being upstreamed)
chipone_icn8505 driver. I guess the _CID and the _DSM are the result of
a copy and paste job when the vendor was building the ACPI tables.
Before this patch the i2c_hid_driver's probe function will fail with a
"hid_descr_cmd failed" error.
This commit makes the i2c_hid_driver's probe function instead silently
ignored devices with an ACPI id of CHPN0001.

Doing `ioctl(HIDIOCGFEATURE)` in a tight loop on a hidraw device
and then disconnecting the device, or unloading the driver, can
cause a NULL pointer dereference.
When a hidraw device is destroyed it sets 0 to `dev->exist`.
Most functions check 'dev->exist' before doing its work, but
`hidraw_get_report()` was missing that check.

The commit 581c4484769e ("HID: input: map digitizer battery usage")
assumed that devices having input (qas opposed to feature) report for
battery strength would report the data on their own, without the need to
be polled by the kernel; unfortunately it is not so. Many wireless mice
do not send unsolicited reports with battery strength data and have to
be polled explicitly. As a complication, stylus devices on digitizers
are not normally connected to the base and thus can not be polled - the
base can only determine battery strength in the stylus when it is in
proximity.
To solve this issue, we add a special flag that tells the kernel
to avoid polling the device (and expect unsolicited reports) and set it
when report field with physical usage of digitizer stylus (HID_DG_STYLUS).
Unless this flag is set, and we have not seen the unsolicited reports,
the kernel will attempt to poll the device when userspace attempts to
read "capacity" and "state" attributes of power_supply object
corresponding to the devices battery.

Implement the same thing for keyboards, so user can

Sony's NSG-MR5U and NSG-MR7U remote controls have a full keyboard and a
touchpad. The keyboard is already supported by the existing Linux
kernel and drivers but the touchpad is not recognized. This patch adds
the coded needed to bring full functionality to the touchpad.
Note that these remotes use the vendor code for SMK even though they are
Sony branded.
Known limitations
- The built-in accelerometers are not supported by these changes
- When the Drag (Fn) key is used as a mouse button, the button is
automatically released when the key begins repeating. There are two
workarounds for this 1) Use the button behind the touchpad instead of
the Drag (Fn) key or 2) Disable the key repeat functionality or
increase the key repeat delay.

This patch changes all references to ELECOM trackballs using their

ELECOM provides multiple series of mice such as EX-G, HUGE, and DEFT.
Although it has not caused conflicts in the driver, there can be more
than one iteration of mice in each series. For example, there are 7
variants of EX-G trackballs but only three (M-XT3URBK, M-XT3DRBK, and
M-XT4DRBK) need a driver to work correctly.
There are also 4 DEFT series trackballs but two of them have the same

This is the mindless scripted replacement of kernel use of POLL*

for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
done
with de-mangling cleanups yet to come.
NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do. But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.
The next patch from Al will sort out the final differences, and we
should be all done.
