The v4l2_m2m_get_vq() never returns a NULL pointer, as the internal get_queue_ctx() helper always returns a non-NULL pointer. Many drivers check the return value against NULL, due to a combination of old code and cargo-cult programming. Even v4l2-mem2mem.c contains unneeded NULL checks. Clarify the API by documenting explicitly that a NULL check is not needed, and simplify the code by removing the unneeded NULL checks from v4l2-mem2mem.c.
