commitc370bb4740upstream. When resuming from low power, the driver attempts to restore the configuration of some pins. This is done by a call to: stm32_pinctrl_restore_gpio_regs(struct stm32_pinctrl *pctl, u32 pin) where 'pin' must be a valid pin value (i.e. matching some 'groups->pin'). Fix the current implementation which uses some wrong 'pin' value.

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.
