Subject: media: bttv: copy vbi_fmt from bttv_fh Author: Deborah Brouwer <[email protected]> Date: Fri Jul 14 19:16:01 2023 -0700 In preparation for the vb2 conversion, copy the vbi format from struct bttv_fh and add it to the main struct bttv. Use vbi format from struct bttv wherever it will be needed after the vb2 conversion which stops using separate bttv file handles altogether. To avoid changing more code than necessary, just leave the vbi format in separate file handles wherever it will be subsequently removed by vb2.
