Herve Codina 76db8a75f0 of: Fix error path in of_parse_phandle_with_args_map() 
commit d7dfa7fde6 upstream.

The current code uses some 'goto put;' to cancel the parsing operation
and can lead to a return code value of 0 even on error cases.

Indeed, some goto calls are done from a loop without setting the ret
value explicitly before the goto call and so the ret value can be set to
0 due to operation done in previous loop iteration. For instance match
can be set to 0 in the previous loop iteration (leading to a new
iteration) but ret can also be set to 0 it the of_property_read_u32()
call succeed. In that case if no match are found or if an error is
detected the new iteration, the return value can be wrongly 0.

Avoid those cases setting the ret value explicitly before the goto
calls.

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.
