[PATCH 2/4 v3] mtd: onenand: samsung: return an error if 'mtd_device_parse_register()' fails

From: Christophe JAILLET
Date: Thu Dec 14 2017 - 01:11:23 EST


If 'mtd_device_parse_register()' fails, we still return 0 which mean
success.
Return the error code instead, as done in all the other error handling
paths.
