For OMAP4 only builds, the omap2_prm_* functions have dummy wrappers to detect incorrect usage. However, several unrelated omap3 PRM functions have made it inside the #else clause of the #ifdef wrapping the omap2_prm stubs, causing them to disappear on OMAP4-only builds. This was unnoticed until the IO chain support was added and introduced a new function in this section which is referenced by omap_hwmod.c: /work/kernel/omap/dev/arch/arm/mach-omap2/omap_hwmod.c: In function '_reconfigure_io_chain': /work/kernel/omap/dev/arch/arm/mach-omap2/omap_hwmod.c:1665:3: error: implicit declaration of function 'omap3xxx_prm_reconfigure_io_chain' [-Werror=implicit-fungiction-declaration] Fix by using the #ifdef to only wrap the omap2_prm functions that need stubs on OMAP4-only builds.
