The return value of max77650_charger_disable() is ignored by all but one caller. That one caller propagates the error code in the platform driver's remove function. The only effect of that is that the driver core emits a generic error message (but still removes the device). As max77650_charger_disable() already emits an error message, this can better be changed to return zero. This is a preparation for making struct platform_driver::remove return void, too.

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.
