issues in just the binder and iio codebases. Included in here are:
- binder driver bugfixes for both the rust and c versions for
reported problems
- lots and lots of iio driver bugfixes for lots of reported issues
(including a hid sensor driver bugfix)
Full details are in the shortlog, all of these have been in linux-next

al3010_scales[] encodes the highest gain range as {0, 1187200}.
For IIO_VAL_INT_PLUS_MICRO, the fractional part must be less than
1000000, so the scale 1.1872 should instead be represented as
{ 1, 187200 }.
Since write_raw() compares the value from userspace against this
table, writing the advertised 1.1872 scale never matches the malformed
entry and returns -EINVAL. As a result, the highest gain range cannot
be selected. Reading the scale in that state also reports the malformed
value.

gp2ap002_read_raw() calls pm_runtime_get_sync() before reading the
lux value, but if gp2ap002_get_lux() fails, it returns directly. This
skips the pm_runtime_put_autosuspend() call at the "out" label,
permanently leaking a runtime PM reference and preventing the device
from autosuspending.
Replace the direct return with a "goto out" to ensure the reference
is properly dropped on the error path.

The function was only used to verify if als_persist is a
TSL2591_PRST_ALS_INT_CYCLE_* value. However, before its call in
tsl2591_write_event_value(), the line
als_persist = tsl2591_persist_lit_to_cycle(period) is executed,
meaning that by the time tsl2591_compatible_als_persist_cycle()
is reached, als_persist is a TSL2591_PRST_ALS_INT_CYCLE_* value,
making the verification pointless.

Add IIO driver for Broadcom APDS9999 ambient light sensor.
The APDS9999 is a digital proximity and RGB sensor with ALS
capability. The driver implements the ALS/Lux functionality
using the green channel, which uses optical coating technology
to approximate the human eye spectral response.
Raw IIO_INTENSITY channels are exposed for red, green, blue,
and IR so userspace can compute its own weighted lux.
Proximity (PS) support is not yet implemented.

Convert several functions to use guard(mutex)()
This avoids manual unlock calls on each return path, drops the goto
in tcs3472_write_event(), and removes 'ret' variables only needed to
return after the unlock.
While the conversion is in progress, take the opportunity to make a
few small cleanups that guard() enables:
- In tcs3472_read_event_config(), replace '!!(...)' with
'(...) ? 1 : 0' for readability.
- In tcs3472_write_event_config(), tcs3472_powerdown() and
tcs3472_resume() use an early return on the I2C
write failure path.

If tcs3472_probe() fails after enabling the chip (by writing PON | AEN
to the ENABLE register), the error paths return without powering down
the device.
Add an 'error_powerdown' label at the end of the cleanup chain that
calls tcs3472_powerdown() to power down the chip. The existing label
cascade is rerouted to fall through to the new label.
Move tcs3472_powerdown() above tcs3472_probe() so the probe can call
it without a forward declaration.
Found by code inspection while reviewing the probe error paths in
preparation for the devm_ conversion.

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.
The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.
This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

Sashiko reported a bug where the si1133_command exits on timeout
without halting the sensor or masking the interrupt. If the sensor
completes the command later, any subsequent command to the sensor
will cause the IRQ handler to complete immediately, returning stale
data to the driver all while the command hasn't finished yet, shifting
all potential reads in the future.
Fix this by masking the IRQ if wait_for_completion_timeout() fails.
When initiating a new command, do a dummy read of the IRQ_STATUS
register and turn the IRQ back on.

Sashiko reported a potential race condition happening when the driver
returns an errno after a timeout in the si1133_command() function. The
premature exit causes the hardware and software counters to become out
of sync by not updating data->rsp_seq, therefore the internal hardware
counter keeps incrementing.
Fix this by adding a call to si1133_cmd_reset_counter() before returning
from timeout.

On the Inspur HS326 laptop(which integrated with HiSilicon M900
processor), if the STK3311-X chip's PS interrupt is configured
in "Recommended interrupt mode", the interrupt cannot be triggered
normally after waking from suspend or hibernation.
In this case, neither disabling and re-enabling the interrupt nor
resetting the PS threshold register can restore the interrupt to
normal operation.
If the interrupt is disabled in suspend() then reset the PS threshold
register and enable the interrupt in resume(). This resolves the issue.

Clean up the included headers in stk3310.c according to the
Include-What-You-Use (IWYU) tool. Remove the generic <linux/kernel.h>
header and add explicit dependencies to improve compilation accuracy.

Sort the included headers alphabetically and group the <linux/iio/*>
headers separately from the generic <linux/*> headers.

Currently in the function opt3001_get_processed(), there is a check
that directly returns -ETIMEDOUT if the conversion IRQ times out,
completely bypassing the err label, leaving ok_to_ignore_lock
permanently true, potentially breaking the device's falling threshold
interrupt detection.
Assign -ETIMEDOUT to the return variable and jump to the error label
to ensure ok_to_ignore_lock is properly reset.

al3320a_read_raw() used to read two adjacent registers
until the driver was modernized using the regmap framework.
That cleanup accidentally replaced the 16-bit word read
with a single byte read. I'm reverting latter.

The events are registered for IIO_LIGHT and not for IIO_INTENSITY.
Use the correct channel type.
When at it, fix minor checkpatch code style warning (alignment).
