[ Upstream commitbb43c8e382] The commit below modified rxe_create_mmap_info() to return ERR_PTR's but didn't update the callers to handle them. Modify rxe_create_mmap_info() to only return ERR_PTR and fix all error checking after rxe_create_mmap_info() is called. Ensure that all other exit paths properly set the error return.

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.
