Remove the IIO specific scaling measurement units from the read functions
and add them inside the ->read_raw() function to keep the read_*() generic.
This way they can be used in other parts of the driver.

The Vishay veml3235 is a low-power ambient light sensor with I2C
interface. It provides a minimum detectable intensity of
0.0021 lx/cnt, configurable integration time and gain, and an additional
white channel to distinguish between different light sources.

The veml3235 is another Vishay ambient light sensor that shares similar
properties with the other sensors covered by this bindings. In this
case, only the compatible, reg, and vdd-supply properties are required,
and the device does not have an interrupt line, like the already
supported veml7700.

The commits in question do not proove that ACPI IDs exist.
Quite likely it was a cargo cult addition while doing that
for DT-based enumeration. Drop most likely fake ACPI IDs.
The to be removed IDs has been checked against the following resources:
1) DuckDuckGo
2) Google
3) MS catalog: https://www.catalog.update.microsoft.com/Search.aspx
This gives no useful results in regard to DSDT, moreover, the official
vendor ID in the registry for Lite-On is LCI.

Device nodes accessed via of_get_compatible_child() require
of_node_put() to be called when the node is no longer required to avoid
leaving a reference to the node behind, leaking the resource.
In this case, the usage of 'tnode' is straightforward and there are no
error paths, allowing for a single of_node_put() when 'tnode' is no
longer required.

Since commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP
boundaries") a mmap() of anonymous memory without a specific address hint
and of at least PMD_SIZE will be aligned to PMD so that it can benefit
from a THP backing page.
However this change has been shown to regress some workloads
significantly. [1] reports regressions in various spec benchmarks, with
up to 600% slowdown of the cactusBSSN benchmark on some platforms. The
benchmark seems to create many mappings of 4632kB, which would have merged
to a large THP-backed area before commit efa7df3e3bb5 and now they are
fragmented to multiple areas each aligned to PMD boundary with gaps
between. The regression then seems to be caused mainly due to the
benchmark's memory access pattern suffering from TLB or cache aliasing due
to the aligned boundaries of the individual areas.
Another known regression bisected to commit efa7df3e3bb5 is darktable [2]
[3] and early testing suggests this patch fixes the regression there as
well.
To fix the regression but still try to benefit from THP-friendly anonymous
mapping alignment, add a condition that the size of the mapping must be a
multiple of PMD size instead of at least PMD size. In case of many
odd-sized mapping like the cactusBSSN creates, those will stop being
aligned and with gaps between, and instead naturally merge again.

When numa balancing is enabled with demotion, vmscan will call
migrate_pages when shrinking LRUs. migrate_pages will decrement the
the node's isolated page count, leading to an imbalanced count when
invoked from (MG)LRU code.
The result is dmesg output like such:
$ cat /proc/sys/vm/stat_refresh
[77383.088417] vmstat_refresh: nr_isolated_anon -103212
[77383.088417] vmstat_refresh: nr_isolated_file -899642
This negative value may impact compaction and reclaim throttling.
The following path produces the decrement:
shrink_folio_list
demote_folio_list
migrate_pages
migrate_pages_batch
migrate_folio_move
migrate_folio_done
mod_node_page_state(-ve) <- decrement
This path happens for SUCCESSFUL migrations, not failures. Typically
callers to migrate_pages are required to handle putback/accounting for
failures, but this is already handled in the shrink code.
When accounting for migrations, instead do not decrement the count when
the migration reason is MR_DEMOTION. As of v6.11, this demotion logic
is the only source of MR_DEMOTION.

Remove my previous work email, and the new one. The previous was never
used in the commit log, so there's no good reason to spare it.

The KX022A provides the accelerometer data in two subsequent registers.
The registers are laid out so that the value obtained via bulk-read of
these registers can be interpreted as signed 16-bit little endian value.
The read value is converted to cpu_endianes and stored into 32bit integer.
The le16_to_cpu() casts value to unsigned 16-bit value, and when this is
assigned to 32-bit integer the resulting value will always be positive.
This has not been a problem to users (at least not all users) of the sysfs
interface, who know the data format based on the scan info and who have
converted the read value back to 16-bit signed value. This isn't
compliant with the ABI however.
This, however, will be a problem for those who use the in-kernel
interfaces, especially the iio_read_channel_processed_scale().
The iio_read_channel_processed_scale() performs multiplications to the
returned (always positive) raw value, which will cause strange results
when the data from the sensor has been negative.
Fix the read_raw format by casting the result of the le_to_cpu() to
signed 16-bit value before assigning it to the integer. This will make
the negative readings to be correctly reported as negative.
This fix will be visible to users by changing values returned via sysfs
to appear in correct (negative) format.

In iio_gts_build_avail_time_table(), it is checked that gts->num_itime is
non-zero, but gts->num_itime is not checked in gain_to_scaletables(). The
variable time_idx is initialized as gts->num_itime - 1. This implies that
time_idx might initially be set to -1 (0 - 1 = -1). Consequently, using
while (time_idx--) could lead to an infinite loop.

Fix reading unsigned data from the AD4000 ADC via the _raw sysfs
attribute by ensuring that *val is set before returning from
ad4000_single_conversion(). This was not being set in any code path
