Thomas Fourier b8a2639341 octeontx2: Fix otx2_dma_map_page() error return code 
commit d998b0e5af upstream.

0 is a valid DMA address [1] so using it as the error value can lead to
errors.  The error value of dma_map_XXX() functions is DMA_MAPPING_ERROR
which is ~0.  The callers of otx2_dma_map_page() use dma_mapping_error()
to test the return value of otx2_dma_map_page(). This means that they
would not detect an error in otx2_dma_map_page().

Make otx2_dma_map_page() return the raw value of dma_map_page_attrs().

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 reStructuredText 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.
