With the change introduced by6ac246105b, the calibration can only be done after the codec probe (but questionable if it is working since 203A_AMP_EN is 0) or when the codec is powered up for audio use, in other cases "AMP is not ready to run calibration" is printed. This changes how this worked before the patch: the codec was force powered on for the duration of the calibration readout, then shut down. So, if a calibration was asked when the codec was active, it would have powered it down? To correct the calibration logic: check if the codec is powered on and if it is not then enable it, do the readout and put it back to disabled. Do this while keeping the dapm locked to avoid interfering with normal operation via DAPM.

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.
