commitb67210cc21upstream. Consider the GPIO controller offset (from "gpio-ranges") to compute the maximum GPIO line number. This fixes an issue where gpio-ranges uses a non-null offset. e.g.: gpio-ranges = <&pinctrl 6 86 10> In that case the last valid GPIO line is not 9 but 15 (6 + 10 - 1) Cc: stable@vger.kernel.org Fixes:67e2996f72("pinctrl: stm32: fix the reported number of GPIO lines per bank") Reported-by: Christoph Fritz <chf.fritz@googlemail.com> Signed-off-by: Fabien Dessenne <fabien.dessenne@foss.st.com> Link: https://lore.kernel.org/r/20211215095808.621716-1-fabien.dessenne@foss.st.com Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
