Found with coccinelle:

No need to set .owner here. The core will do it.

2fbb91d73f ramips: correct page read return value of the mt7621 nand driver
read_page() need to return maximum number of bitflips instead of the
accumulated number. Change takes from upstream mt7621 u-boot [1].

 * @read_page:  function to read a page according to the ECC generator
 *              requirements; returns maximum number of bitflips
 *              corrected in any single ECC step, -EIO hw error

level to debug:

2f2e81a4ea ramips: move mt7621_nand driver to files
The patch was rejected by upstream. The mtk_nand driver should be
modified to support the mt7621 flash controller instead. As there is no
newer version to backport, or no upstream version to fix bugs, let's
move the driver to the files dir under the ramips target. This makes it
easier to make changes to the driver while waiting for mt7621 support to
land in mtk_nand.
