exynos_fdt_map_chipid() was recently added with: cbf08b9 (ARM: EXYNOS:
Consolidate exynos4 and exynos5 machine files) and generates this warning:

arch/arm/mach-exynos/exynos.c: In function ‘exynos_fdt_map_chipid’:
arch/arm/mach-exynos/exynos.c:208:6: warning: assignment discards ‘const’ qualifier from pointer target type [enabled by default]

Constify 'reg' to fix it.
