[ Upstream commit10628e3ecf] This function is supposed to return zero on success or negative error codes on error. Unfortunately, there is a bug so it sometimes returns non-zero, positive numbers on success. I noticed this bug during review and I can't test it. It does appear that the return is sometimes propogated back to _regmap_read() where all non-zero returns are treated as failure so this may affect run time.

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.
