Instead of calling the gpiochip's set_config() callback directly and checking its existence every time - just add a new routine that performs this check internally. Call it in gpio_set_config() and gpiod_set_transitory(). Also call it in gpiod_set_debounce() and drop the check for chip->set() as it's irrelevant to this config option.

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.
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.
