[PATCH] media: dvb_ringbuffer: Add memory barriers

Implement memory barriers according to Documentation/circular-buffers.txt: - use smp_store_release() to update ringbuffer read/write pointers - use smp_load_acquire() to load write pointer on reader side - use ACCESS_ONCE() to load read pointer on writer side This fixes data stream corruptions
