At least ASUS Zenbook 14 (2023) and ASUS Zenbook 14 Pro (2023) are affected.
The touchscreen reports a battery status of 0% and jumps to 1% when a
stylus is used.
The device ID was added and the battery ignore quirk was enabled for it.

The Elan eKTH5015M touch controller found on the Lenovo ThinkPad X13s
shares the VCC33 supply with other peripherals that may remain powered
during suspend (e.g. when enabled as wakeup sources).
The reset line is also wired so that it can be left deasserted when the
supply is off.
This is important as it avoids holding the controller in reset for
extended periods of time when it remains powered, which can lead to
increased power consumption, and also avoids leaking current through the
X13s reset circuitry during suspend (and after driver unbind).
Use the new 'no-reset-on-power-off' devicetree property to determine
when reset needs to be asserted on power down.
Notably this also avoids wasting power on machine variants without a
touchscreen for which the driver would otherwise exit probe with reset
asserted.

joycon_leds_create() has a ida_alloc() call. So if an error occurs after
it, a corresponding ida_free() call is needed, as already done in the
.remove function.
This is not 100% perfect, because if ida_alloc() fails, then
'ctlr->player_id' will forced to be U32_MAX, and an error will be logged
when ida_free() is called.
Considering that this can't happen in real life, no special handling is
done to handle it.

Syzkaller hit a warning [1] in a call to implement() when trying
to write a value into a field of smaller size in an output report.
Since implement() already has a warn message printed out with the
help of hid_warn() and value in question gets trimmed with:
...
value &= m;
...
WARN_ON may be considered superfluous. Remove it to suppress future
syzkaller triggers.

kernel test robot reported build error due to a pointer type mismatch:
.../ishtp/loader.c:172:8: error: incompatible pointer types passing
'__le64 *' (aka 'unsigned long long *') to parameter of type
'dma_addr_t *' (aka 'unsigned int *')
The issue arises because the driver, which is primarily intended for
x86-64, is also built for i386 when COMPILE_TEST is enabled.
Resolve type mismatch by using a temporary dma_addr_t variable to hold
the DMA address. Populate this temporary variable in dma_alloc_coherent()
function, and then convert and store the address in the
fragment->fragment_tbl[i].ddr_adrs field in the correct format.
Similarly, convert the ddr_adrs field back to dma_addr_t when freeing
the DMA buffer with dma_free_coherent().

Kbuild conventionally uses $(obj)/ for generated files, and $(src)/ for
checked-in source files. It is merely a convention without any functional
difference. In fact, $(obj) and $(src) are exactly the same, as defined
in scripts/Makefile.build:
src := $(obj)
When the kernel is built in a separate output directory, $(src) does
not accurately reflect the source directory location. While Kbuild
resolves this discrepancy by specifying VPATH=$(srctree) to search for
source files, it does not cover all cases. For example, when adding a
header search path for local headers, -I$(srctree)/$(src) is typically
passed to the compiler.
This introduces inconsistency between upstream and downstream Makefiles
because $(src) is used instead of $(srctree)/$(src) for the latter.
To address this inconsistency, this commit changes the semantics of
$(src) so that it always points to the directory in the source tree.
Going forward, the variables used in Makefiles will have the following
meanings:
$(obj) - directory in the object tree
$(src) - directory in the source tree (changed by this commit)
$(objtree) - the top of the kernel object tree
$(srctree) - the top of the kernel source tree
Consequently, $(srctree)/$(src) in upstream Makefiles need to be replaced
with $(src).

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.

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

This pen is compatible with multiple Wacom tablets, but we only add support
for the Intuos Pro 2 M, as this is the one our user reported the bug
against.
We can not generically add all compatible Wacom tablets as we are
writing the offsets by hand.
The point of this HID-BPF program is to work around a firmware limitation
where the pressure is repeated every other report.
Given that we know this will happen, we can change the first new pressure
information with the mean compared to the previous one. This way we
smooth the incoming pressure without losing information.

This commit adds a fix for XPPen Artist 24 where the second button on
the pen is used as an eraser.
It's a "feature" from Microsoft, but it turns out that it's actually
painful for artists. So we ship here a HID-BPF program that turns this
second button into an actual button.
Note that the HID-BPF program is not directly loaded by the kernel itself
but by udev-hid-bpf[0]. But having the sources here allows us to also
integrate tests into tools/testing/selftests/hid to ensure the HID-BPF
program are actually tested.

This label was left behind when the wake-up logic was moved from
i2c_hid_set_power to i2c_hid_probe_address. Clean it up as it causes
warnings-as-errors builds to fail.

This patch enhances the firmware reset handler in the Intel Integrated
Sensor Hub (ISH) driver. Previously, the ISH firmware would send a
MNG_RESET_NOTIFY message in response to an empty IPC message from the
ish_wakeup function. With the introduction of the feature to load ISH
firmware from the host on the LunarLake platform, the ISH bootloader
now involves the IPC function. This results in an additional
MNG_RESET_NOTIFY message being sent by ISH bootloader after power on.
Consequently, the driver receives two MNG_RESET_NOTIFY messages during
system boot up. This can disrupt the dev->dev_state during the first
reset flow due to the subsequent reset notify message.
To address this, the patch modifies the fw_reset_work_fn function to skip
the execution of ishtp_reset_compl_handler during the first reset flow if
a reset is pending. The ishtp_reset_compl_handler will then be executed
during the second reset flow, ensuring the dev->dev_state is not disrupted.

Starting from the Lunar Lake generation, the ISH firmware has been
divided into two components for better space optimization and increased
flexibility. These components include a bootloader that is integrated
into the BIOS, and a main firmware that is stored within the operating
system's file system.
Introduce support for loading ISH main firmware from host. This feature is
applicable for Lunar Lake and later generation.
Current intel-ishtp-loader, is designed for Chrome OS based systems which
uses core boot and has different firmware loading method. For non chrome
systems the ISH firmware loading uses different method.
Key differences include:
1. The new method utilizes ISHTP capability/fixed client to enumerate the
firmware loader function. It does not require a connection or flow control,
unlike the method used in Chrome OS, which is enumerated as an ISHTP
dynamic client driver, necessitating connect/disconnect operations and flow
control.
2. The new method employs a table to describe firmware fragments, which are
sent to ISH in a single operation. Conversely, the Chrome OS method sends
firmware fragments in multiple operations within a loop, sending only one
fragment at a time.
Additionally, address potential error scenarios to ensure graceful failure
handling.
- Firmware Not Found: Triggers if request_firmware() fails, leaving ISH in
a waiting state.
Recovery: Re-insmod the ISH drivers to retry.
- DMA Buffer Allocation Failure: Occurs during prepare_dma_bufs(), leading
to ISH waiting state. Allocated resources are released.
Recovery: Re-insmod the ISH drivers to retry.
- Incorrect Firmware Image: Causes ISH to refuse loading after three failed
attempts.
Recovery: A platform reset is required.
Please refer to the [Documentation](Documentation/hid/intel-ish-hid.rst)
for the details on flows.

The logic in dualshock4_get_calibration_data() used uninitialised data
in case of a failed kzalloc() for the transfer buffer.
The solution is to group all business logic and all sanity checks
together, and jump only to the latter in case of an error.
While we're at it, factor out the axes' labelling, since it must happen
either way for input_report_abs() to succeed later on.
Thanks to Dan Carpenter for the Smatch static checker warning.
