Manually add sysfs groups after the faux_device_ops's probe succeeds. Likewise remove these groups just before calling the faux_devices_ops's remove callback. This approach approximates the order in which the driver core adds and removes the driver's .dev_groups of a device to avoid lifetime issues. This is done specifically to avoid using the device's .groups member, which adds groups before the device is even registered to the bus. This lets consumers of this API, initialize resources on the .probe callback and then use them inside is_visible/show/store methods, through dev_get_drvdata() without races. Cc: Rafael J.

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.
