commit fb5cc65f973661241e4a2b7390b429aa7b330c69 upstream.
We register a devm action to call adp5589_clear_config() and then pass
the i2c client as argument so that we can call i2c_get_clientdata() in
order to get our device object. However, i2c_set_clientdata() is only
being set at the end of the probe function which means that we'll get a
NULL pointer dereference in case the probe function fails early.
Fixes: 30df385e35 ("Input: adp5589-keys - use devm_add_action_or_reset() for register clear")

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.
