Théo Lebrun 1f40990563 gpio: nomadik: fix offset bug in nmk_pmx_set()
[ Upstream commit 53cf6b72e0 ]

Previously, the statement looked like:

    slpm[x] &= ~BIT(g->grp.pins[i]);

Where:
 - slpm is a unsigned int pointer;
 - g->grp.pins[i] is a pin number. It can grow to more than 32.

The expected shift amount is a pin bank offset.

This bug does not occur on every group or pin: the altsetting must be
NMK_GPIO_ALT_C and the pin must be 32 or above. It might have occured.
For example, in pinctrl-nomadik-db8500.c, pin group i2c3_c_2 has the
right altsetting and pins 229 and 230.

Fixes: dbfe8ca259 ("pinctrl/nomadik: implement pin multiplexing")

README

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.
