[ Upstream commit 427c70dec738318b7f71e1b9d829ff0e9771d493 ]
Randomly a Lenovo Z13 will trigger a kernel warning traceback from this
condition:
```
if (WARN_ON((profile < 0) || (profile >= ARRAY_SIZE(profile_names))))
```
This happens because thinkpad-acpi always assumes that
convert_dytc_to_profile() successfully updated the profile. On the
contrary a condition can occur that when dytc_profile_refresh() is called
the profile doesn't get updated as there is a -EOPNOTSUPP branch.
Catch this situation and avoid updating the profile. Also log this into
dynamic debugging in case any other modes should be added in the future.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
