If twl4030_exit_irq() returns an error, the effect is that the caller (twl_remove()) forwards the error to the i2c core without unregistering its dummy slave devices. This only makes the i2c core emit another error message and then it still removes the device. In this situation it doesn't make sense to abort the remove cleanup and not unregister the slave devices. So do that. Then return value is actually unused and twl4030_exit_irq() can better be changed to return no value at all.

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.
