The efivar ops are typically registered at subsys init time so that they are available when efivarfs is registered at module init time. Other efivars implementations, such as Google SMI, exist and can currently be built as modules which means that efivar may not be available when efivarfs is initialised. Move the efivar availability check from module init to when the filesystem is mounted to allow late registration of efivars.

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.
