Benjamin Tissoires 14f437a1d7 HID: logitech-hidpp: rename battery level into capacity
The power_supply term for the percentage is capacity. Capacity level
can be given when non accurate mileage is provided by the device, so
better stick to the terms used in power_supply.

Benjamin Tissoires eb626c5732 HID: logitech-hidpp: handle battery events in hidpp_raw_hidpp_event()
Battery events are reported through HID++, so we need to be sure

Without this, we might receive keyboard events that looks just like

Benjamin Tissoires 843c624eef HID: logitech-hidpp: rework probe path for unifying devices
Unifying devices are different from others because they can probed

Instead of having conditionals while attempting to read the device name

the quirk MT_QUIRK_VALID_IS_CONFIDENCE it is using is not working very
properly. This quirk is originally designed for some WIn7 touchscreens. Use
of this for a Win8 Precision Touchpad will cause unexpected pointer jumping

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.

Trent Lloyd 282bf1fe6d HID: usbhid: quirks for Corsair RGB keyboard & mice (K70R, K95RGB, M65RGB, 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.

Gabriele Mazzotta 0a0f5b7e5b HID: multitouch: Synchronize MT frame on reset_resume
input_mt_get_slot_by_key() requires input_mt_sync_frame() to be called
at each frame. Do it when releasing the touches, or else we won't get
a proper slot number after mt_reset_resume().

Benjamin Tissoires 580549ef6b HID: wacom: fix Bamboo ONE oops
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.

Josh Boyer ea36ae0910 HID: lenovo: Don't use stack variables for DMA buffers
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.

Alan Stern 972e6a993f HID: usbhid: fix inconsistent reset/resume/reset-resume behavior
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.

Cyan Ogilvie d30596737e HID: wiimote: Fix wiimote mp scale linearization
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
