commit 5a062c3c3b82004766bc3ece82b594d337076152 upstream.
This should be >= pmx->soc->ngroups instead of > to avoid an out of
bounds access. The pmx->soc->groups[] array is allocated in
tegra_pinctrl_probe().
Fixes: c12bfa0fee65 ("pinctrl-tegra: Restore SFSEL bit when freeing pins")

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.
