[PATCH 19/22] mtd: nand: hisi504: return error code of nand_scan_ident() on error

From: Masahiro Yamada
Date: Fri Nov 04 2016 - 06:42:40 EST


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