After exiting the while loop, we checked if recovery was successful and sent a STOP to the clients. Meanwhile however, we send a STOP after every pulse, so it is not needed after the loop. If we move the check for a free bus to the end of the while loop, we can shorten and simplify the logic. It is still ensured that at least one STOP will be sent to the wire even if SDA was not stuck low.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
