The behavior of HONOR MagicBook Art 14 touchpad is not consistent
after reboots, as sometimes it reports itself as a touchpad, and
sometimes as a mouse.
Similarly to GLO-GXXX it is possible to call MT_QUIRK_FORCE_GET_FEATURE as a
workaround to force set feature in mt_set_input_mode() for such special touchpad
device.

By default the track point does not work on the Asus Expertbook B2402FVA.
From libinput record i got the ID of the track point device:
evdev:
# Name: ASUE1201:00 04F3:32AE
# ID: bus 0x18 vendor 0x4f3 product 0x32ae version 0x100
I found that the track point is functional, when i set the
MT_CLS_WIN_8_FORCE_MULTI_INPUT_NSMU class for the reported device.

Some Plantronics headset as the below send an unexcept opposite
volume key's HID report for each volume key press after 200ms, like
unecepted Volume Up Key following Volume Down key pressed by user.
This patch adds a quirk to hid-plantronics for these devices, which
will ignore the second unexcepted opposite volume key if it happens
within 220ms from the last one that was handled.
Plantronics EncorePro 500 Series (047f:431e)
Plantronics Blackwire_3325 Series (047f:430c)
The patch was tested on the mentioned model, it shouldn't affect
other models, however, this quirk might be needed for them too.
Auto-repeat (when a key is held pressed) is not affected per test
result.

error: uninitialized symbol 'rv'.
Initialize 'rv' to 0 to prevent undefined behavior from uninitialized

With the introduction of commit e42ac14180 ("bpf: Check unsupported ops
from the bpf_struct_ops's cfi_stubs"), a HID-BPF struct_ops containing
a .hid_hw_request() or a .hid_hw_output_report() was failing to load
as the cfi stubs were not defined.
Fix that by defining those simple static functions and restore HID-BPF
functionality.
This was detected with the HID selftests suddenly failing on Linus' tree.

This reverts commit 9184b17fbc ("dt-bindings: input: Goodix SPI HID
Touchscreen") because it duplicates existing binding leadings to errors:
goodix,gt7986u.example.dtb:
touchscreen@0: compatible: 'oneOf' conditional failed, one must be fixed:
['goodix,gt7986u'] is too short
'goodix,gt7375p' was expected
This was reported on mailing list on 6th of September, but no reaction
happened from contributor or maintainer to fix it.
Therefore let's drop binding which breaks and duplicates existing one.

Pull random number generator updates from Jason Donenfeld:
"Originally I'd planned on sending each of the vDSO getrandom()
architecture ports to their respective arch trees. But as we started
to work on this, we found lots of interesting issues in the shared
code and infrastructure, the fixes for which the various archs needed
to base their work.
So in the end, this turned into a nice collaborative effort fixing up
issues and porting to 5 new architectures -- arm64, powerpc64,
powerpc32, s390x, and loongarch64 -- with everybody pitching in and
commenting on each other's code. It was a fun development cycle.
This contains:
- Numerous fixups to the vDSO selftest infrastructure, getting it
running successfully on more platforms, and fixing bugs in it.
- Additions to the vDSO getrandom & chacha selftests. Basically every
time manual review unearthed a bug in a revision of an arch patch,
or an ambiguity, the tests were augmented.
By the time the last arch was submitted for review, s390x, v1 of
the series was essentially fine right out of the gate.
- Fixes to the the generic C implementation of vDSO getrandom, to
build and run successfully on all archs, decoupling it from
assumptions we had (unintentionally) made on x86_64 that didn't
carry through to the other architectures.
- Port of vDSO getrandom to LoongArch64, from Xi Ruoyao and acked by
Huacai Chen.
- Port of vDSO getrandom to ARM64, from Adhemerval Zanella and acked
by Will Deacon.
- Port of vDSO getrandom to PowerPC, in both 32-bit and 64-bit
varieties, from Christophe Leroy and acked by Michael Ellerman.
- Port of vDSO getrandom to S390X from Heiko Carstens, the arch
maintainer.
While it'd be natural for there to be things to fix up over the course
of the development cycle, these patches got a decent amount of review
from a fairly diverse crew of folks on the mailing lists, and, for the
most part, they've been cooking in linux-next, which has been helpful
for ironing out build issues.
In terms of architectures, I think that mostly takes care of the
important 64-bit archs with hardware still being produced and running
production loads in settings where vDSO getrandom is likely to help.
Arguably there's still RISC-V left, and we'll see for 6.13 whether
they find it useful and submit a port"
