The "Get Current Connector Alternate Mode" command is optional. The PPM
will set the "Not Supported Indicator" flag in the command status, if it
isn't supported (-EOPNOTSUPP error is reported by ucsi_exec_command()).
As this command is optional, this case shouldn't be treated as an error:
- Improve the error message to display the error code.
- Turn the not supported case into a dev_dbg instead of a dev_err.
Note: This error message is no longer seen upstream, after:

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.
