The fuzz present on the distance and tilt axes is noticable when a puck is
present, and userspace (specifically libinput) would like the ability to
filter out the noise. To facilitate this, we assign a fuzz value of '1'
for the distance and tilt axes. This is large enough to cover most of the
natural variation in distance value as the puck is moved around, and
enough to cover the jitter in rotation (reported through tilt axes) when
the puck is left alone.

K70RGB, K65RGB)
These devices feature multiple interfaces/endpoints: a legacy BIOS/boot
interface (endpoint 0x81), as well as 2 corsair-specific keyboard interfaces
(endpoint 0x82, 0x83 IN/0x03 OUT) and an RGB LED control interface (endpoint
0x84 IN/0x04 OUT)
Because the extra 3 interfaces are not of subclass USB_INTERFACE_SUBCLASS_BOOT,
HID_QUIRK_NOGET is not automatically set on them and a 10s timeout per-endpoint
(30s per device) occurs initialising reports on boot. We configure
HID_QUIRK_NO_INIT_REPORTS for these devices.
Additionally the left-side G1-G18 macro keys on the K95RGB generate output on
the un-opened 0x82/0x83 endpoints which causes the keyboard to stop responding
waiting for this event to be collected. We enable HID_QUIRK_ALWAYS_POLL to
prevent this situation from occurring.

The 'size' variable is not really needed, and we can also shift constant
in the loop body when masking off existing bits.
Also we do not have to use 64 bit calculations if we take an extra
branch.

LED core takes care of handling failed calls to thingm_let_set.
- print error message in set_brightness_delayed or
- pass error to caller in led_set_brightness_sync
Also the error message here doesn't provide any hint what actually

A tablet PC booted into Windows may have its pen/touch hardware switched
into "Wacom mode" similar to what we do with explicitly-supported hardware.
Some devices appear to maintain this state across reboots, preventing their
use with the generic HID driver. This patch adds support for detecting the
presence of the mode switch feature report used by devices based on the G9
and G11 chips and has the HID codepath always attempt to reset the device
back to sending standard HID reports.

Looks like recent changes in the Wacom driver made the Bamboo ONE crashes.
The tablet behaves as if it was a regular Bamboo device with pen, touch
and pad, but there is no physical pad connected to it.
The weird part is that the pad is still sending events and given that
there is no input node connected to it, we get anull pointer exception.

The lenovo_send_cmd_cptkbd function uses a stack variable to submit
commands via hid_hw_raw_request. Eventually this gets to the
usb_hcd_map_urb_for_dma function, which causes a warning to be thrown
if the CONFIG_DMA_API_DEBUG option is enabled.
Fix this by allocating a temporary buffer instead.

The usbhid driver has inconsistently duplicated code in its post-reset,
resume, and reset-resume pathways.
reset-resume doesn't check HID_STARTED before trying to
restart the I/O queues.
resume fails to clear the HID_SUSPENDED flag if HID_STARTED
isn't set.
resume calls usbhid_restart_queues() with usbhid->lock held
and the others call it without holding the lock.
The first item in particular causes a problem following a reset-resume
if the driver hasn't started up its I/O. URB submission fails because
usbhid->urbin is NULL, and this triggers an unending reset-retry loop.
This patch fixes the problem by creating a new subroutine,
hid_restart_io(), to carry out all the common activities. It also
adds some checks that were missing in the original code:
After a reset, there's no need to clear any halted endpoints.
After a resume, if a reset is pending there's no need to
restart any I/O until the reset is finished.
After a resume, if the interrupt-IN endpoint is halted there's
no need to submit the input URB until the halt has been
cleared.

The wiimote motion plus gyros use two scales to report fast and slow
rotation - below 440 deg/s uses 8192/440 units / deg/s, and above uses
8192/2000 units / deg/s.
Previously this driver attempted to linearize the two by scaling the fast
rate by 18 and the slow by 9, but this results in a scale of
8192*9/440 = ~167.564 for slow and 8192*18/2000 = 73.728 for fast.
Correct the fast motion scale factor so that both report ~167.564
units / deg/s

If wireless_work() wants to reuse parse_and_register(), we need to have
it declared after this function.
No functional changes.

Simplifies the .probe() and will allow to reuse this path in the future.
Few things are reshuffled in .probe():
- init wacom struct earlier
- then retrieve the report descriptor
- then parse it and allocate/register inputs.

stylus_in_proximity was introduced to support touch arbitration
before in range was supported. With in range event, the logic
changed. stylus_in_proximity should be set for both in prox and
in range events.
To finish a clean touch arbitration logic, we should send touch
up (if it was down) before posting any general pen events.

Microsoft Wireless Comfort Keyboard has vendor specific My Favorites
1-5 keys. Linux already supports this buttons on other MS keyboards by
MS_ERGONOMY quirk. So apply MS_ERGONOMY quirk to USB PID 0x00e3
(Microsoft Wireless Optical Desktop Receiver 3.0A). After this
My Favorites 1..5 keys will be reported as KEY_F14..KEY_F15 events.

When reviewing another thingm patch Benjamin Tissoires pointed out
the following: "The problem here is that hid_hw_start() is called
before thingm_version() which allows user space to briefly introduce
races between thingm_version() and any hidraw requests.
The mutex will not help here as it is initialized after hid_hw_start()
and only used for protecting the concurrent access of the rgb."
Avoid this possible issue by calling hid_hw_start() later in the
probe function.

Reading from the device consists of two operations: sending the read
command and the actual read from the device. If the device is accessed
in between we might read wrong data. Therefore protect the full sequence
of both operations with a mutex.
Also change the semantics of thingm_recv to include both operations.
