The original code tried to find a console that has CON_BOOT _or_ CON_ENABLED flag set. The flag CON_ENABLED is set to all registered consoles, so in this case this check is always true, even for the CON_BOOT consoles. The initial intent of the kgdboc_earlycon_init was to get a console early (CON_BOOT) or later on in the process (CON_ENABLED). The code was using for_each_console macro, meaning that all console structs were previously registered on the printk() machinery. At this point, any console found on for_each_console is safe for kgdboc_earlycon_init to use. Dropping the check makes the code cleaner, and avoids further confusion by future readers of the code.

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.
