Currently hid-debug's hid_resolv_event prints questions marks for
all entries without explicit mapping information. This makes
debugging unnecessarily complicated as multiple different
keys may simply result in the same uninformative output.
Some common event codes are deliberately not defined in
input-event-codes.h. For example the 16th gamepad key.
Instead, print the hexadecimal codes for all events without symbolic
names.

This device sometimes doesn't send touch release signals when moving
from >=4 fingers to <4 fingers. Using MT_QUIRK_NOT_SEEN_MEANS_UP instead
of MT_QUIRK_ALWAYS_VALID makes sure that no touches become stuck.
MT_QUIRK_FORCE_MULTI_INPUT is not necessary for this device, but does no
harm.

Export the sleepable kfuncs we have on HID-BPF in tracing bpf programs,
but with the condition of being used in a sleepable context.
This allows to use the bpf_timer when used in a sleepable context
through bpf_timer_set_sleepable_cb() and initiate work from a device event.

It can be interesting to inject events from BPF as if the event were
to come from the device.
For example, some multitouch devices do not all the time send a proximity
out event, and we might want to send it for the physical device.
Compared to uhid, we can now inject events on any physical device, not
just uhid virtual ones.

We currently only export hid_hw_raw_request() as a BPF kfunc.
However, some devices require an explicit write on the Output Report
instead of the use of the control channel.
So also export hid_hw_output_report to BPF

In af93a167eda9, i2c_hid_parse was changed to continue with reading the
report descriptor before waiting for reset to be acknowledged.
This has lead to two regressions:
1. We fail to handle reset acknowledgment if it happens while reading
the report descriptor. The transfer sets I2C_HID_READ_PENDING, which
causes the IRQ handler to return without doing anything.
This affects both a Wacom touchscreen and a Sensel touchpad.
2. On a Sensel touchpad, reading the report descriptor this quickly
after reset results in all zeroes or partial zeroes.
The issues were observed on the Lenovo Thinkpad Z16 Gen 2.
The change in question was made based on a Microsoft article[0] stating
that Windows 8 *may* read the report descriptor in parallel with
awaiting reset acknowledgment, intended as a slight reset performance
optimization. Perhaps they only do this if reset is not completing
quickly enough for their tastes?
As the code is not currently ready to read registers in parallel with a
pending reset acknowledgment, and as reading quickly breaks the report
descriptor on the Sensel touchpad, revert to waiting for reset
acknowledgment before proceeding to read the report descriptor.

Hid-debug's rdesc output for a game controller contained a few question
marks and numeric IDs instead of the expected descriptive names.
This happens because:
1) the mapping data is missing event codes defined in input-event-codes.h
2) HID usages aren't up to date
3) hid_resolv_usage fails to account for the sensor pages' modifiers
Add missing event codes and update HID to HUT 1.5.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

This patch is regarding the recent addition of support for the NSO
controllers to hid-nintendo. All controllers are working correctly with the
exception of the N64 controller, which is being identified as a mouse by
udev. This results in the joystick controlling the mouse cursor and the
controller not being detected by games.
The reason for this is because the N64's C buttons have been attributed to
BTN_FORWARD, BTN_BACK, BTN_LEFT, BTN_RIGHT, which are buttons typically
attributed to mice.
This patch changes those buttons to controller buttons, making the
controller be correctly identified as such.

The flag I2C_HID_READ_PENDING is used to serialize I2C operations.
However, this is not necessary, because I2C core already has its own
locking for that.
More importantly, this flag can cause a lock-up: if the flag is set in
i2c_hid_xfer() and an interrupt happens, the interrupt handler
(i2c_hid_irq) will check this flag and return immediately without doing
anything, then the interrupt handler will be invoked again in an
infinite loop.
Since interrupt handler is an RT task, it takes over the CPU and the
flag-clearing task never gets scheduled, thus we have a lock-up.
Delete this unnecessary flag.

As Linus suggested this enables pidfs unconditionally. A key property to
retain is the ability to compare pidfds by inode number (cf. [1]).
That's extremely helpful just as comparing namespace file descriptors by
inode number is. They are used in a variety of scenarios where they need
to be compared, e.g., when receiving a pidfd via SO_PEERPIDFD from a
socket to trivially authenticate a the sender and various other
use-cases.
For 64bit systems this is pretty trivial to do. For 32bit it's slightly
more annoying as we discussed but we simply add a dumb ida based
allocator that gets used on 32bit. This gives the same guarantees about
inode numbers on 64bit without any overflow risk. Practically, we'll
never run into overflow issues because we're constrained by the number
of processes that can exist on 32bit and by the number of open files
that can exist on a 32bit system. On 64bit none of this matters and
things are very simple.
If 32bit also needs the uniqueness guarantee they can simply parse the
contents of /proc/<pid>/fd/<nr>. The uniqueness guarantees have a
variety of use-cases. One of the most obvious ones is that they will
make pidfiles (or "pidfdfiles", I guess) reliable as the unique
identifier can be placed into there that won't be reycled. Also a
frequent request.
Note, I took the chance and simplified path_from_stashed() even further.
Instead of passing the inode number explicitly to path_from_stashed() we
let the filesystem handle that internally. So path_from_stashed() ends
up even simpler than it is now. This is also a good solution allowing
the cleanup code to be clean and consistent between 32bit and 64bit. The
cleanup path in prepare_anon_dentry() is also switched around so we put
the inode before the dentry allocation. This means we only have to call
the cleanup handler for the filesystem's inode data once and can rely
->evict_inode() otherwise.
Aside from having to have a bit of extra code for 32bit it actually ends
up a nice cleanup for path_from_stashed() imho.
Tested on both 32 and 64bit including error injection.
