HID: bpf: add a v6.11+ compatible BPF fixup for the XPPen ACK05 remote
With v6.11+, we can actually call hid_hw_output_report() and put the device
into raw mode, thus getting accurate events without being messed up.
Technically we could do the same on v6.10, but given that wayland, gnome
and KDE are still not capable of handling the dial, and that v6.10 is EOL,
we can safely save a little bit of compilation by only allowing v6.11+.
We can easily export the battery information to userspace by adding a
dedicated report. However, we need to cheat on the kernel to force it
not to query the battery by making the physical collection a stylus. The
kernel will then only rely on the events it gets from the device.

HID: bpf: new hid_bpf_async.h common header
The purpose is to simplify the use of bpf_wq to defer blocking
operations in a sleepable context. Compared to a more "classic"
async approach, there is no sync mechanism to wait for the async
to finish.
The "simple" API is the following:
```
static int HID_BPF_ASYNC(async_fun)(struct hid_bpf_ctx *hctx)
{
bpf_printk("%s", __fun__);
return 0;
}
SEC("syscall")
int probe(struct hid_bpf_probe_args *ctx)
{
ctx->retval = HID_BPF_ASYNC_INIT(async_fun);
return 0;
}
SEC(HID_BPF_DEVICE_EVENT)
int BPF_PROG(event_handler, struct hid_bpf_ctx *hctx)
{
/* async_fun() can be called now, it's not a sleepable
* function in this example
*/
async_fun(hctx);
/* but we can also delay the call by 10 ms */
HID_BPF_ASYNC_DELAYED_CALL(async_fun, hctx, 10);
return 0;
}
HID_BPF_OPS(xppen_ack05_remote) = {
.hid_device_event = (void *)event_handler,
};
```

HID: bpf: Suppress bogus F13 trigger on Sirius keyboard full fan shortcut
The TUXEDO Sirius 16 Gen1 and the TUXEDO Sirius 16 Gen2 Notebooks have an
additional "fan" key next to F12.
Pressing it alone sends a F14 key press which can be bound by user space.
Pressing it while holding the FN key triggers two things:
- The EC firmware locks the fan speed of the internal fans at 100%
- F13 key press is registered which by default is already bound in xkb and
desktop environments (e.g. in KDE Plasma it launches system settings)
To avoid this unexpected double duty of the FN shortcut, this bpf program
suppresses the F13 key press.

Pretty much similar to the Inspiroy 2, but with 2 wheels and 8 buttons.
This bpf also works in both normal and vendor mode. If the device is

HID: bpf: add a driver for the Huion Inspiroy 2S (H641P)
This is a a driver for the Huion Inspiroy 2S in both modes (firmware mode
and tablet mode). This device has 6 buttons and a wheel, all of which
send key combinations (see the comments for the defaults). Luckily the
device is quite limited in that it only supports one button down at a
time, so with this BPF we can simply remap the 8 possible report IDs to
our own custom-built report descriptor.
If the device is in tablet mode (e.g. using huion-switcher it sends
everything through the vendor report instead). This BPF program converts
both, depending which devices you attach to you get both. Or if you
attach to all hid devices you get a duplicate device but it'll work
either way.
This BPF should be mostly compatible for the M and L as well though they
have more buttons so the rdescs will need some minor rework.

HID: bpf: Add a HID report composition helper macros
These macros make it slightly easier and more modular to create
a HID report descriptor from scratch. Since they carry the annotation
we don't need to comment it and they cannot get stale.
For comparison, before we had this:
0x15, 0x00, // Logical Minimum (0)
0x25, 0x01, // Logical Maximum (1)
0x95, 0x04, // Report Count (4)
0x75, 0x01, // Report Size (1)
Now we can write this as:
LogicalRange_i8(0, 1)
ReportCount(4)
ReportSize(1)
Because these macros are for creating new report descriptors,
some bits aren't directly exposed. e.g in the example above:
there is a logical range as one macro that sets both min and max.
There is seldom a good use case for skipping either anyway.
These macros will need to be expanded over time.
For Usage Pages and Usage IDs, we use a tool to parse the HUT JSON
(attached to the HUT 1.5 PDF [1]) and generate all #defines for all
usage pages and usages in the form:
#define UsagePage_Foo_Bar
#define Usage_FB_SomeOrOther
Where the FB is simply the acronym based on the capital letters in the
Usage Page name or the first three letters, whichever makes slightly
more sense.

HID: bpf: add in-tree HID-BPF fix for the Huion Kamvas Pro 19
This tablets gets a lot of things wrong:
- the secondary button is reported through Secondary Tip Switch
- the third button is reported through Invert
Fortunately, before entering eraser mode, (so Invert = 1),
the tablet always sends an out-of-proximity event.
So we can detect that single event and:
- if there was none but the invert bit was toggled: this is the
third button
- if there was this out-of-proximity event, we are entering
eraser mode, and we will until the next out-of-proximity.

HID: bpf: add in-tree HID-BPF fix for the XBox Elite 2 over Bluetooth
When using the XBox Wireless Controller Elite 2 over Bluetooth,
the device exports the paddle on the back of the device as a single
bitfield value of usage "Assign Selection".
The kernel doesn't process those usages properly and report KEY_UNKNOWN
for it.
SDL doesn't know how to interprete that KEY_UNKNOWN and thus ignores the
paddles.
Given that over USB the kernel uses BTN_TRIGGER_HAPPY[5-8], we
can tweak the report descriptor to make the kernel interprete it properly:
- we need an application collection of gamepad (so we have to close the
current Consumer Control one)
- we need to change the usage to be buttons from 0x15 to 0x18
