Subject: [PATCH 4.19 183/206] mtd: rawnand: Pass a nand_chip object to nand_scan()
From: Boris Brezillon <boris.brezillon@...tlin.com>
[ Upstream commit 00ad378f304a091ab2e2df5f944892a6ed558610 ]
Let's make the raw NAND API consistent by patching all helpers to take
a nand_chip object instead of an mtd_info one.
We start with nand_scan().
