If WM0 latency is zero we need to bump it (and the WM1+ latencies) but a fixed amount. But any WM1+ level with zero latency must not be touched since that indicates that corresponding WM level isn't supported. Currently the loop doing that adjustment does work, but only because the previous loop modified the num_levels used as the loop boundary. This all seems a bit too fragile. Remove the num_levels adjustment and instead adjust the read latency loop to abort when it encounters a zero latency value.

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 reStructuredText 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.
