Hello, This small patch series exposes the vb2_queue_is_busy() function, currently internal to videobuf2-v4l2.c, to drivers. The rationale is explained in patch 1/3, and the first use case shown in 3/3: it allows implementing additional checks at streamon time while keeping the owner check first (as it's cheap, compared to other checks that can be more expensive). Patch 2/3 is a driver-by cleanup.
