Linux kernel source tree

The component helpers already expose the bound status in debugfs, but at times it might be necessary to also check that state in the kernel and act differently depending on the result. For example the shutdown handler of a drm-driver might need to stop a whole output pipeline if the drm device is up and running, but may run into problems if that drm-device has never been set up before, for example because the binding deferred. So add a little helper that returns the bound status for a componet device.

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.
