The ->prepare()/->unprepare() hooks are now legacy, we no longer accept new drivers supporting them. The only remaining controllers using them acquires a per-chip mutex, which should not interfere with the rest of the operation done in the core. As a result, we should be safe to reorganize these helpers to first perform the preparation, before acquiring the core locks. This is necessary in order to be able to improve the locking mechanism in the core (coming next). No side effects are expected.

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.
