 regulator: rt5759: fix OOB in validate_desc() 
I got the following OOB report:

 BUG: KASAN: slab-out-of-bounds in validate_desc+0xba/0x109
 Read of size 8 at addr ffff888107db8ff0 by task python3/253
 Call Trace:

  rt5759_probe+0x3a0/0x4ac [rt5759_regulator]

The desc used in validate_desc() is passed from 'reg_cfg.ena_gpiod',
which is not initialized. Fix this by initializing 'reg_cfg' to 0.

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.
