The original implementation from commit b504882da539
("USB: add Freescale high-speed USB SOC device controller driver")
returned NULL on failure and an allocated + initialized struct fsl_udc on
success. The current code introduced in commit 4365831dadfe
("USB: fsl_usb2_udc: Get max ep number from DCCPARAMS register") only
provides partial initialization as well as returning 0 on success and -1
on failures. The function documentation is updated accordingly.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
