software_resume can be called either from an init call in the boot code, or from sysfs once the system has finished booting, and the two invocation methods this can't race with each other. For the latter case we did just parse the suspend device manually, while the former might not have one. Split software_resume so that the search only happens for the boot case, which also means the special lockdep nesting annotation can go away as the system transition mutex can be taken a little later and doesn't have the sysfs locking nest inside it.

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.
