In most contexts '-1' doesn't really mean much to the casual observer. In almost all cases, it's better to use a human readable define. In this case PLATFORM_DEVID_* defines have already been provided for this purpose. While we're here, let's be specific about the 'MFD devices' which failed. It will help when trying to distinguish which of the 2 sets of sub-devices we actually failed to register.

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.
