Dan Carpenter 15a007e7ae iio: adc: ad4030: fix error pointer dereference in probe()
The intention here was obviously to return an error if devm_regmap_init()
fails, but the return statement was accidentally left out.  This leads to
an error pointer dereference when we call:

	ret = ad4030_detect_chip_info(st);

Add the return statement.

Fixes: ec25cf6f1e ("iio: adc: ad4030: add support for ad4632-16 and ad4632-24")

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 reStructuredText 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.
