Subject: [PATCH 34/43] mtd: plat_nand.c: use mtd_device_parse_register
Date: Wed, 8 Jun 2011 20:05:43 +0400 [thread overview]
Message-ID: <1307549152-7085-35-git-send-email-dbaryshkov@gmail.com> (raw)
In-Reply-To: <1307549152-7085-1-git-send-email-dbaryshkov@gmail.com>
Replace custom invocations of parse_mtd_partitions and mtd_device_register
with common mtd_device_parse_register call. This would bring: standard
handling of all errors, fallback to default partitions, etc.
