Subject: media: videobuf2-core: clear memory related fields in
__vb2_plane_dmabuf_put()
Author: Yunke Cao <yun...@chromium.org>
Date: Wed Aug 14 11:06:40 2024 +0900
Clear vb2_plane's memory related fields in __vb2_plane_dmabuf_put(),
including bytesused, length, fd and data_offset.
Remove the duplicated code in __prepare_dmabuf().
