In the case of the test pattern generator that only happens if the two lines are using different patterns. So precalculate the average between two pattern lines: one of pattern P and one of pattern P + 1. That way there is no need to do any on-the-fly downsampling: it's all done in the precalculate phase. This patch also implements horizontal downsampling in the precalculate phase. The only thing that needs to be done is to half the width since the actual downsampling happens when two pixels at a time are generated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is step one of supporting horizontal and vertical downsampling. This just adds support for the h/vdownsampling fields and it increases the maximum number of planes to 3. Currently none of the planar formats need horizontal or vertical downsampling, so this change has no effect at the moment.

ERROR: "skb_push" [drivers/media/radio/wl128x/fm_drv.ko] undefined! ERROR: "skb_pull" [drivers/media/radio/wl128x/fm_drv.ko] undefined! Making the driver dependency explicit solves randconfig build problems and makes it more obvious to the reader.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The available (i.e. not used) buffers are returned by stk1160_clear_queue(), on the stop_streaming() path. However, this is insufficient and the current buffer must be released as well. Fix it.
