When runtime-pm is disabled, we get a few harmless warnings:
drivers/char/hw_random/omap3-rom-rng.c:65:12: error: unused function 'omap_rom_rng_runtime_suspend' [-Werror,-Wunused-function] drivers/char/hw_random/omap3-rom-rng.c:81:12: error: unused function 'omap_rom_rng_runtime_resume' [-Werror,-Wunused-function]
Mark these functions as __maybe_unused so gcc can drop them silently.
