Eryk Brol 918698d5c2 drm/amd/display: Return the number of bytes parsed than allocated
[why & how]
Previously we were returning the number of bytes allocated
for a write buffer from debugfs and when manually used it wouldn't
rise any errors, but it wouldn't match the size of the parameters
passed from userspace.

In successful case return the size passed by usermode otherwise
the error code is returned. That simplifies the parser helper
and removes a potential error of returning mismatched input size.

README

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.
