The videobuf2-core did not zero the 'planes' array in __qbuf_userptr() and __qbuf_dmabuf(). That's now memset to 0. Without this the reserved array in struct v4l2_plane would be non-zero, causing v4l2-compliance errors. More serious is the fact that data_offset was not handled correctly: - for capture devices it was never zeroed, which meant that it was uninitialized. Unless the driver sets it it was a completely random number. With the memset above this is now fixed. - __qbuf_dmabuf had a completely incorrect length check that included data_offset. - in __fill_vb2_buffer in the DMABUF case the data_offset field was unconditionally copied from v4l2_buffer to v4l2_plane when this should only happen in the output case. - in the single-planar case data_offset was never correctly set to 0. The single-planar API doesn't support data_offset, so setting it to 0 is the right thing to do. This too is now solved by the memset. All these issues were found with v4l2-compliance.
