[PATCH 18/22] mtd: nand: cafe: return error code of nand_scan_ident() on error

From: Masahiro Yamada
Date: Fri Nov 04 2016 - 06:42:12 EST


The nand_scan_ident() returns an appropriate error value when it
fails. Use it instead of the fixed error code -ENXIO.
(This driver is already doing so for nand_scan_tail().)
