Charles Han be2c39883b power: supply: max14577: Handle NULL pdata when CONFIG_OF is not set
[ Upstream commit 2937f5d2e2 ]

When the kernel is not configured  CONFIG_OF, the max14577_charger_dt_init
function returns NULL. Fix the max14577_charger_probe functionby returning
-ENODATA instead of potentially passing a NULL pointer to PTR_ERR.

This fixes the below smatch warning:
max14577_charger_probe() warn: passing zero to 'PTR_ERR'

Fixes: e30110e9c9 ("charger: max14577: Configure battery-dependent settings from DTS and sysfs")

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.
