pinctrl_generic_add_group() doesn't check the result of radix_tree_insert() despite they both may return a negative error code. Linus Walleij said he has copied the radix tree code from kernel/irq/ where the functions calling radix_tree_insert() are *void* themselves; I think it makes more sense to propagate the errors from radix_tree_insert() upstream if we can do that...

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.
