When fall-through warnings was enabled by default the following warning
was starting to show up:
../drivers/pinctrl/pinctrl-rockchip.c: In function ‘rockchip_gpio_set_config’:
../drivers/pinctrl/pinctrl-rockchip.c:2783:3: warning: this statement may fall
through [-Wimplicit-fallthrough=]
rockchip_gpio_set_debounce(gc, offset, true);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../drivers/pinctrl/pinctrl-rockchip.c:2795:2: note: here
default:
^~~~~~~
Rework so that the compiler doesn't warn about fall-through. Add
'return -ENOTSUPP;' to match the comment.
Fixes: d93512ef0f0e ("Makefile: Globally enable fall-through warning")

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.
