In an effort to enable -Wcast-function-type in the top-level Makefile to support Control Flow Integrity builds, there are the need to remove all the function callback casts. To do this, create a new macro called ACPI_DECLARE_SUBTABLE_PROBE_ENTRY to initialize the acpi_probe_entry struct using the probe_subtbl field instead of the probe_table field. This is a previous work to be able to modify the IRQCHIP_ACPI_DECLARE macro to use this new defined macro. Even though these two commented fields are part of a union, this is necessary to avoid function cast mismatches. That is, due to the IRQCHIP_ACPI_DECLARE invocations use as last parameter a function with the protoype "int (*func)(struct acpi_subtable_header *, const unsigned long)" it's necessary that this macro initialize the probe_subtbl field of the acpi_probe_entry struct and not the probe_table field.

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.
