hwrng: omap3-rom - Fix unused function warnings
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. Fixes: 8d9d4bdc495f ("hwrng: omap3-rom - Use runtime PM instead of custom functions") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Reviewed-by: Sebastian Reichel <sebastian.reichel@collabora.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
