Danish Khateeb 5b864f8db0 pps: generators: wake up PPS_GEN_FETCHEVENT readers on unregister ... A reader sleeping in PPS_GEN_FETCHEVENT waits for the next event, but no event comes after pps_gen_unregister_source(), so the reader sleeps until it gets a signal. A PPS_GEN_FETCHEVENT issued after the unregister sleeps the same way. Wake up the readers on unregister, and make PPS_GEN_FETCHEVENT fail with -ENODEV once the generator is gone, like the other ioctls. The wait checks info without info_lock, so clear it with WRITE_ONCE().
