Subject: [PATCH 07/10] video: fbdev: use resource_size
Date: Wed, 1 Jan 2020 18:49:47 +0100 [thread overview]
Message-ID: <1577900990-8588-8-git-send-email-Julia.Lawall@inria.fr> (raw)
In-Reply-To: <1577900990-8588-1-git-send-email-Julia.Lawall@inria.fr>
Use resource_size rather than a verbose computation on
the end and start fields.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
<smpl>
@@ struct resource ptr; @@
- (ptr.end - ptr.start + 1)
+ resource_size(&ptr)
</smpl>
