Presumably there's a header file somewhere that defines the interface to
irq-s3c24xx.c that other code in arch/arm/plat-s3c24xx is using to
initialize it. That header should be moved somewhere public (i.e.
outside {mach,plat}-*/include/{mach,plat}). However, you then end up
with a header file per IRQ driver in that public location. So, Thomas
Petazzoni started working on a solution for that:
