Replace the deprecated[1] use of a 1-element array in struct
MR_HOST_DEVICE_LIST with a modern flexible array.
One binary difference appears in megasas_host_device_list_query():
struct MR_HOST_DEVICE_LIST *ci;
...
ci = instance->host_device_list_buf;
...
memset(ci, 0, sizeof(*ci));
The memset() clears only the non-flexible array fields. Looking at the rest
of the function, this appears to be fine: firmware is using this region to
communicate with the kernel, so it likely never made sense to clear the
first MR_HOST_DEVICE_LIST_ENTRY.

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.
