Subject: [PATCH 3/3] MTD/pxa: use resource_size(res) for pxa2xx-flash
Date: Sat, 05 Jun 2010 14:48:57 +0800	[thread overview]
Message-ID: <4C09F359.1000100@gmail.com> (raw)

The size calculation is end - start + 1. But,sometimes, the '1' can
be forgotten carelessly, witch will have potential risk, so use resource_size
should be good habit.
