Subject: [PATCH 26/43] mtd: davinci_nand.c: use mtd_device_parse_register
Date: Wed,  8 Jun 2011 20:05:35 +0400	[thread overview]
Message-ID: <1307549152-7085-27-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.
