Peng Fan 65379adf7d remoteproc: imx_rproc: Fix invalid loaded resource table detection 
[ Upstream commit 26aa529501 ]

imx_rproc_elf_find_loaded_rsc_table() may incorrectly report a loaded
resource table even when the current firmware does not provide one.

When the device tree contains a "rsc-table" entry, priv->rsc_table is
non-NULL and denotes where a resource table would be located if one is
present in memory. However, when the current firmware has no resource
table, rproc->table_ptr is NULL. The function still returns
priv->rsc_table, and the remoteproc core interprets this as a valid loaded
resource table.

Fix this by returning NULL from imx_rproc_elf_find_loaded_rsc_table() when
there is no resource table for the current firmware (i.e. when
rproc->table_ptr is NULL). This aligns the function's semantics with the
remoteproc core: a loaded resource table is only reported when a valid
table_ptr exists.

With this change, starting firmware without a resource table no longer
triggers a crash.

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.
