Subject: [Bug 215177] New: Stop exporting platform_profile interface for Lenovo T14/P14s Gen2 AMD

            Bug ID: 215177
           Summary: Stop exporting platform_profile interface for Lenovo
                    T14/P14s Gen2 AMD
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.15.5
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Platform_x86
          Assignee: drivers_platform_x86@kernel-bugs.osdl.org
          Reporter: bjoern.daase@gmail.com
        Regression: No

The T14/P14s Gen2 AMD (and maybe more?) have a completely broken platform
profile implementation. While advertising three profiles, they do not change
anything. See
https://forums.lenovo.com/t5/Other-Linux-Discussions/T14-AMD-subpar-CPU-performance/m-p/5089829?page=1#5386521
for details.

As some user space software (e.g. platform-profiles-daemon) expects them to
work correctly when they are available, they should not be exported for broken
devices.

Therefore, I suggest to stop exporting a platform_profile interface for the
Lenovo T14/P14s Gen2 AMD.
