[PATCH 177/204] mtd: rawnand: Pass a nand_chip object to nand_release()

From: Boris Brezillon boris.brezillon@bootlin.com

[ Upstream commit 59ac276f22270fb2094910f9a734c17f41c25e70 ]

Let's make the raw NAND API consistent by patching all helpers to take a nand_chip object instead of an mtd_info one.

Now is nand_release()'s turn.
