At present, dma_buf_export() takes a series of parameters, which
makes it difficult to add any new parameters for exporters, if required.
Make it simpler by moving all these parameters into a struct, and pass
the struct * as parameter to dma_buf_export().

The video_device debug field has been renamed to dev_debug, resulting in
a compilation failure. As v4l2 debugging is supposed to be controlled
through a sysfs attribute created by the v4l2 core, there's no need to
