Subject: [PATCH 5/8] UBI: check max_beb_per1024 value in ubi_attach_mtd_dev
Date: Fri, 17 Aug 2012 16:35:21 +0200	[thread overview]
Message-ID: <1345214124-5478-6-git-send-email-richard.genoud@gmail.com> (raw)
In-Reply-To: <1345214124-5478-1-git-send-email-richard.genoud@gmail.com>

max_beb_per1024 shouldn't be negative, and a 0 value will be treated as
the default value.
