Neither uart_do_autoconfig(), nor uart_wait_modem_status() can return -ENOIOCTLCMD. The ENOIOCTLCMD checks are there to check if 'cmd' matched against TIOCSERCONFIG, and TIOCMIWAIT respectively. (With 0 or error in 'ret', it does not matter.) Therefore, the code can simply return from the TIOCSERCONFIG and TIOCMIWAIT spots immediately. To be more explicit, use 'if' instead of switch-case for those single values. And return without jumping to the 'out' label -- it can be removed too.

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.
