Colin Ian King cd56a51413 staging: mt7621-pinctrl: fix uninitialized variable ngroups
Currently the for_each_node_with_property loop us incrementing variable
ngroups however it was not initialized and hence will contain garbage.
Fix this by initializing ngroups to zero.

Detected with static analysis with cppcheck:

drivers/staging/mt7621-pinctrl/pinctrl-rt2880.c:89]: (error) Uninitialized
variable: ngroups

Fixes: e12a1a6e08 ("staging: mt7621-pinctrl: refactor rt2880_pinctrl_dt_node_to_map function")

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.
