For callbacks configuring the state of the components (trigger, set_params, ack and set_metadata) simplify the code a little and make intention clearer by aborting as soon as an error is encountered. The operation has already failed and there is nothing to be gained from processing the callbacks on additional components. The operations currently abort after the callbacks, so this simply shortens the error path. For callbacks returning information from the driver (copy, get_metadata, pointer, get_codec_caps, get_caps and get_params) only look for the first callback provided, currently the code will call every callback only returning the information provided by the last. Since we can only return one set of data, it makes no sense to request the data from every component. Again this just makes the currently supported feature set a little more clear.

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.
