The previous fix for more comprehensive runtime PM calls turned out to
be not good as hoped; a few calls including pm_runtime_enable() and
pm_runtime_disable() are rather utterly superfluous for PCI devices,
even triggering a kernel error message. Better to drop those calls.
Note that the problem we wanted to solve with that commit seems
irrelevant with the fix itself; the original bug (a GPF at
azx_remove()) was likely a regression by the recent PCI core cleanup,
and the buggy PCI change has been already reverted. So basically we
were scratching a wrong surface. OTOH, making the runtime PM calls
symmetric for both probe and remove is more consistent, and maybe
that's a sensible outcome.

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.
