7295a996fd platform/x86: dell-sysman: Fix reference leak
If a duplicate attribute is found using kset_find_obj(),
a reference to that attribute is returned. This means
that we need to dispose it accordingly. Use kobject_put()
to dispose the duplicate attribute in such a case.

Compile-tested only.

This function escapes certain special characters like \n.  So if the
last character in the string is a '\n' then it gets changed into two
characters '\' and '\n'.  But maybe we only have space for the '\' so
we need to check for that.

The "conv_dst_size" variable is always less than or to equal the "size"
variable.  It's easier to just check "conv_dst_size" instead of checking
both.

5d36931f0f platform/x86: system76: Handle new KBLED ACPI methods
System76 EC since system76/ec@9ac513128a detects if the keyboard is
white or RGB backlit via `RGBKB-DET#` at run-time instead of being set
at compile-time. As part of this, the brightness of white-only backlit
keyboards was also changed to behave more like the RGB-backlit
keyboards: a value between 0 and 255 instead of a firmware-defined
level.

The EC ACPI methods in coreboot have been updated for this new
functionality only, removing the old behavior.

This should preserve behavior as we roll out new firmware with these
changes included and users update to it.

The DT of_device.h and of_platform.h date back to the separate

As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and

917f543407 platform/x86: simatic-ipc: add CMOS battery monitoring
Siemens Simatic Industrial PCs can monitor the voltage of the CMOS
battery with two bits that indicate low or empty state. This can be GPIO
or PortIO based.
Here we model that as a hwmon voltage. The core driver does the PortIO
and provides boilerplate for the GPIO versions. Which are split out to
model runtime dependencies while allowing fine-grained kernel
configuration.

e0b278e7b5 platform/x86: asus-wmi: expose dGPU and CPU tunables for ROG
Expose various CPU and dGPU tunables that are available on many ASUS
ROG laptops. The tunables shown in sysfs will vary depending on the CPU
and dGPU vendor.

All of these variables are write only and there is no easy way to find
what the defaults are. In general they seem to default to the max value
the vendor sets for the CPU and dGPU package - this is not the same as
the min/max writable value. Values written to these variables that are
beyond the capabilities of the CPU are ignored by the laptop.
