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.
The first patch creates a 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 to avoid function cast mismatches.
The second patch modifies the IRQCHIP_ACPI_DECLARE macro to use the new defined macro ACPI_DECLARE_SUBTABLE_PROBE_ENTRY instead of the macro ACPI_DECLARE_PROBE_ENTRY. Also, modifies the prototype of the functions used by the invocation of the IRQCHIP_ACPI_DECLARE macro to match all the parameters.
Changelog v1->v2 - Add more details in the commit changelog to clarify the changes (Marc Zyngier) - Declare a new macro called ACPI_DECLARE_SUBTABLE_PROBE_ENTRY (Marc Zyngier) - In the IRQCHIP_ACPI_DECLARE use the new defined macro (Marc Zyngier)
Changelog v2->v3 - Remove the cast of the macro ACPI_DECLARE_SUBTABLE_PROBE_ENTRY (Marc Zyngier) - Change the prototype of the functions used by the invocation of the macro IRQCHIP_ACPI_DECLARE (Marc Zyngier) - Split the changes in two patches. - Add these two lines, to give credit to Marc Zyngier Signed-off-by: Marc Zyngier <maz@kernel.org> Signed-off-by: Oscar Carter <oscar.carter@gmx.com>
