Simple changes that replace v4l2-specific data with vb2 data in videobuf2-core. enum v4l2_buf_type --> int enum v4l2_memory --> enum vb2_memory VIDEO_MAX_FRAME --> VB2_MAX_FRAME VIDEO_MAX_PLANES --> VB2_MAX_PLANES struct v4l2_fh *owner --> void *owner V4L2_TYPE_IS_MULTIPLANAR() --> is_multiplanar V4L2_TYPE_IS_OUTPUT() --> is_output Signed-off-by: Junghak Sung <jh1009.sung@samsung.com> Signed-off-by: Geunyoung Kim <nenggun.kim@samsung.com> Acked-by: Seung-Woo Kim <sw0312.kim@samsung.com> Acked-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
