[ Upstream commit 1b58acfd067ca16116b9234cd6b2d30cc8ab7502 ]
When da9055_device_init() fails after regmap_add_irq_chip()
succeeds but mfd_add_devices() fails, the error handling path
only calls mfd_remove_devices() but forgets to call
regmap_del_irq_chip(). This results in a resource leak.
Fix this by adding regmap_del_irq_chip() to the error path so
that resources are released properly.

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.
