From bd93a3af82d5175a86badf7bc0e30d17cc6469ce Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 4 Nov 2016 19:43:04 +0900 Subject: [PATCH] mtd: nand: omap2: return error code of nand_scan_ident/tail() on error The nand_scan_ident/tail() returns an appropriate error value when it fails. Use it instead of the fixed error code -ENXIO.
