Thanks for the heads up.
The patch introducing the new macros fails to include linux/module.h
(arm64 gets away with it by luck, while arm fails to compile).
I'm fixing it with the patch below.
M.

Subject: [PATCH] irqchip: Fix IRQCHIP_PLATFORM_DRIVER_* compilation by
including module.h
The newly introduced IRQCHIP_PLATFORM_DRIVER_* macros expand into
module-related macros, but do so without including module.h.
Depending on the driver and/or architecture, this happens to work,
or not.
Unconditionnaly include linux/module.h to sort it out.
Fixes: f3b5e608ed6d ("irqchip: Add IRQCHIP_PLATFORM_DRIVER_BEGIN/END and IRQCHIP_MATCH helper macros")
