Subject[PATCH 5.4 418/453] mtd: spinand: Fix OOB read
Date
From: Miquel Raynal <miquel.raynal@bootlin.com>

commit 868cbe2a6dcee451bd8f87cbbb2a73cf463b57e5 upstream.

So far OOB have never been used in SPI-NAND, add the missing memcpy to
make it work properly.

Fixes: 7529df465248 ("mtd: nand: Add core infrastructure to support SPI NANDs")
