Hans de Goede 9c9c33ea4c power: supply: bq27xxx: Fix kernel crash on IRQ handler register error 
[ Upstream commit cdf10ffe8f626d8a2edc354abf063df0078b2d71 ]

When registering the IRQ handler fails, do not just return the error code,
this will free the devm_kzalloc()-ed data struct while leaving the queued
work queued and the registered power_supply registered with both of them
now pointing to free-ed memory, resulting in various kernel crashes
soon afterwards.

Instead properly tear-down things on IRQ handler register errors.

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.
