Sergey Senozhatsky bac63f1239 media: vb2: set cache sync hints when init buffers ... We need to set ->need_cache_sync_on_prepare and ->need_cache_sync_on_finish when we initialize vb2 buffer. Currently these flags are set/adjusted only in V4L2's vb2_queue_or_prepare_buf(), which means that for the code paths that don't use V4L2 vb2 will always tell videobuf2 core to skip ->prepare() and ->finish() cache syncs/flushes. Fix this by setting cache sync hints for new buffers; except VB2_MEMORY_DMABUF buffers, for which DMA exporter syncs caches.
