From c8cae35572b6132e7c3fbb708ebee4b84e29bbed Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 4 Nov 2016 19:43:07 +0900 Subject: [PATCH] mtd: nand: hisi504: return error code of nand_scan_ident() on error 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().)
