The return type of ARRAY_SIZE() is size_t, so we have to use %zu instead of %lu to avoid this warning:
drivers/gpu/drm/msm/msm_gpu.c: In function 'msm_gpu_init': drivers/gpu/drm/msm/msm_gpu.c:742:31: error: format '%lu' expects argument of type 'long unsigned int', but argument 7 has type 'unsigned int' [-Werror=format=]
The warning it otherwise harmless as size_t is always the same size as unsigned long in all supported architectures, but gcc doesn't know that.
