Dynamic BIOS SAR driver exposing dynamic SAR information from BIOS
The Dynamic SAR (Specific Absorption Rate) driver uses ACPI DSM
(Device Specific Method) to communicate with BIOS and retrieve
dynamic SAR information and change notifications. The driver uses
sysfs to expose this data to userspace via read and notify.
Sysfs interface is documented in detail under:
Documentation/ABI/testing/sysfs-driver-intc_sar

Some devices may expose non-functioning entries that are reserved for
future use. These entries have zero size. Ignore them during probe.

Use the new i2c_acpi_client_count() helper, this
results in a nice cleanup.

The 'objs' is for user space tools, for the kernel modules
we should use 'y'.

skl_int3472_handle_gpio_resources()
This function returns negative error codes, zero (to indicate that
everything has been completed successfully) and one (to indicate that
more resources need to be handled still).
This code prints an uninitialized error message when the function
returns one which potentially leads to an Oops.

Since we have started collecting Intel x86 specific drivers in their own
folder, move intel_cht_int33fe to its own subfolder there.
