led_banks contains LED module number(s) that should be grouped into the
module bank. led_banks is 0-initialized.
By checking the led_banks entries for 0, un-set entries are detected.
But a 0-entry also indicates that LED module 0 should be grouped into the
module bank.
By only iterating over the available entries no check for unused entries
is required and LED module 0 can be added to bank.

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.
