Subject: [PATCH 4.19 15/49] mtd: rawnand: sunxi: Fix the probe error path

From: Miquel Raynal <miquel.raynal@...tlin.com>

commit 3d84515ffd8fb657e10fa5b1215e9f095fa7efca upstream.

nand_release() is supposed be called after MTD device registration.
Here, only nand_scan() happened, so use nand_cleanup() instead.

Fixes: 1fef62c1423b ("mtd: nand: add sunxi NAND flash controller support")
