Subject: [PATCH v2 3/7] UBI: accept empty string for vid_hdr_offs parameter
Date: Mon, 20 Aug 2012 14:09:17 +0200	[thread overview]
Message-ID: <1345464561-24464-4-git-send-email-richard.genoud@gmail.com> (raw)
In-Reply-To: <1345464561-24464-1-git-send-email-richard.genoud@gmail.com>

as a new parameter (max_beb_per1024) will come in next patches, it's
better to accept empty string value so that we can do:
mtd.ubi=2,,25
