Have you tried loading and using some of these modules with older -RT kernels? If they have been using init_MUTEX_LOCKED on RT semaphores, they should have BUG & Oops. Recent -RT kernels have added extra check for this during linking. The fact that you are prevented from building these modules is a Good Thing(TM). Maybe these drivers should be using completions instead of semaphores. A quick fix would be changing the 'struct semaphore' to 'struct compat_semaphore'.
