Nobody checks for the bool returned by these functions. At the same time: a) the functions set the respective num_foo to zero on error and b) callers honour that variable. Just drop the return type - it's useless. Note: this is an ABI break. Signed-off-by: Emil Velikov <emil.velikov@collabora.com> Reviewed-by: Daniel Stone <daniels@collabora.com>
