Subject: [PATCH] video: s3c2410fb: use resource_size()
Date: Tue, 17 May 2011 09:45:38 +0000	[thread overview]
Message-ID: <1305625538-32302-1-git-send-email-jg1.han@samsung.com> (raw)

This patch uses the resource_size help function instead of
manually calculating the resource size. It can reduce the chance
of introducing off-by-one errors.
