[PATCH 5.7 142/244] mtd: rawnand: oxnas: Release all devices in the _remove() path

[Greg Kroah-Hartman]

From: Miquel Raynal <miquel.ray...@bootlin.com>

commit 0a5f45e57e35d0840bedb816974ce2e63406cd8b upstream.

oxnans_nand_remove() should release all MTD devices and clean all NAND
devices, not only the first one registered.

Fixes: 668592492409 ("mtd: nand: Add OX820 NAND Support")
