Subject: [PATCH 2/2] mtd: onenand: samsung: return an error if 'mtd_device_parse_register()' fails
Date: Fri, 8 Dec 2017 22:11:05 +0100 [thread overview]
Message-ID: <ef95e7cafe155e80f80808072d84456dd9bbd712.1512765898.git.christophe.jaillet@wanadoo.fr> (raw)

In-Reply-To: <cover.1512765898.git.christophe.jaillet@wanadoo.fr>
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.
