nand_release() is supposed be called after MTD device registration. Here, only nand_scan() happened, so use nand_cleanup() instead.
There is no Fixes tag applying here as the use of nand_release() in this driver predates by far the introduction of nand_cleanup() in commit d44154f969a4 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources") which makes this change possible. However, pointing this commit as the culprit for backporting purposes makes sense.
