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.
