Subject: [PATCH 1/6] HID: elecom: add support for TrackBall 056E:011C
Make function buttons on ELECOM M-HT1DRBK trackball mouse work. This model
has two devices with different device IDs (010D and 011C). Both of
them misreports the number of buttons as 5 in the report descriptor, even
though they have 8 buttons. hid-elecom overwrites the report to fix them,
but supports only on 010D and does not work on 011C. This patch fixes
011C in the similar way but with specialized position parameters.
In fact, it is sufficient to rewrite only 17th byte (05 -> 08). However I
followed the existing way.

Subject: [PATCH 3/6] HID: core: Fix deadloop in hid_apply_multiplier.
The initial value of hid->collection[].parent_idx if 0. When
Report descriptor doesn't contain "HID Collection", the value
remains as 0.
In the meanwhile, when the Report descriptor fullfill
all following conditions, it will trigger hid_apply_multiplier
function call.
1. Usage page is Generic Desktop Ctrls (0x01)
2. Usage is RESOLUTION_MULTIPLIER (0x48)
3. Contain any FEATURE items
The while loop in hid_apply_multiplier will search the top-most
collection by searching parent_idx == -1. Because all parent_idx
is 0. The loop will run forever.
There is a Report Descriptor triggerring the deadloop

Subject: [PATCH 4/6] HID: logitech: Disable hi-res scrolling on USB
On some Logitech mice, such as the G903, and possibly the G403, the HID
events are generated on a different interface to the HID++ one.
If we enable hi-res through the HID++ interface, the HID interface
wouldn't know anything about it, and handle the events as if they were
regular scroll events, making the mouse unusable.
Disable hi-res scrolling on those devices until we implement scroll
events through HID++.

Subject: [PATCH 5/6] HID: amd_sfh: if no sensors are enabled, clean up
It was reported that commit b300667b33b2 ("HID: amd_sfh: Disable the
interrupt for all command") had caused increased resume time on HP Envy
x360.
Before this commit 3 sensors were reported, but they were not actually
functional. After this commit the sensors are no longer reported, but
also the resume time increased.
To avoid this problem explicitly look for the number of disabled sensors.
If all the sensors are disabled, clean everything up.
