The file name: Documentation/ABI/testing/sysfs-platform_profile.rst
should be, instead: Documentation/userspace-api/sysfs-platform_profile.rst.
Update its cross-reference accordingly.
Fixes: a2ff95e018f1 ("ACPI: platform: Add platform profile support")
Fixes: 8e0cbf356377 ("Documentation: Add documentation for new platform_profile sysfs attribute")

Some devices, including most Microsoft Surface devices, have a platform
profile somewhere inbetween balanced and performance. More specifically,
adding this profile allows the following mapping on Surface devices:
Vendor Name Platform Profile
------------------------------------------
Battery Saver low-power
Recommended balanced
Better Performance balanced-performance
Best Performance performance

Add an object pointer to handler callbacks to avoid the need for
drivers to have a global variable to get to their driver-data
struct.

Drop the const qualifier from the static global cur_profile
pointer declaration.
This is a preparation patch for passing the cur_profile pointer as
parameter to the profile_get() and profile_set() callbacks so that
drivers dynamically allocating their driver-data struct, with their
platform_profile_handler struct embedded, can use this pointer to
get to their driver-data.
Note this also requires dropping the const from the pprof
platform_profile_register() function argument. Dropping this
const is not a problem, non of the queued up consumers of
platform_profile_register() actually pass in a const pointer.

This is the initial implementation of the platform-profile feature.
It provides the details discussed and outlined in the
sysfs-platform_profile document.
Many modern systems have the ability to modify the operating profile to
control aspects like fan speed, temperature and power levels. This
module provides a common sysfs interface that platform modules can register
against to control their individual profile options.
