Dan Carpenter 69696951de iio: ssp_sensors: fix error code in ssp_print_mcu_debug()
commit 4170d3dd1467e9d78cb9af374b19357dc324b328 upstream.

The ssp_print_mcu_debug() function should return negative error codes on
error.  Returning "length" is meaningless.  This change does not affect
runtime because the callers only care about zero/non-zero.

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.
