[media] media: videobuf2: Restructure vb2_buffer
Remove v4l2 stuff - v4l2_buf, v4l2_plane - from struct vb2_buffer. Add new member variables - bytesused, length, offset, userptr, fd, data_offset - to struct vb2_plane in order to cover all information of v4l2_plane. struct vb2_plane { <snip> unsigned int bytesused; unsigned int length; union { unsigned int offset; unsigned long userptr; int fd; } m; unsigned int data_offset; } Replace v4l2_buf with new member variables - index, type, memory - which are common fields for buffer management. struct vb2_buffer { <snip> unsigned int index; unsigned int type; unsigned int memory; unsigned int num_planes; struct vb2_plane planes[VIDEO_MAX_PLANES]; <snip> }; v4l2 specific fields - flags, field, timestamp, timecode, sequence - are moved to vb2_v4l2_buffer in videobuf2-v4l2.c struct vb2_v4l2_buffer { struct vb2_buffer vb2_buf; __u32 flags; __u32 field; struct timeval timestamp; struct v4l2_timecode timecode; __u32 sequence; }; 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>
