Don't populate the read-only array fsm_state on the stack at run time, instead make it static const, this reduces the object code size as the data is placed on the data segment and this removes the need to have code to set the array up on each call. Note that making the size of the strings to a more optimal 11 bytes long does not seem to reduce the overall size. Making the array an array of pointers to the strings increases the code size due to the dereferencing overhead. Simplify the array access with &fsm_state[info->state][0] with the simpler expression fsm_state[info->state] to clean up 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.
