Subject: [PATCH 03/10] fbdev: s1d13xxxfb: use resource_size
Date: Wed,  1 Jan 2020 18:49:43 +0100	[thread overview]
Message-ID: <1577900990-8588-4-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 these changes is as follows:
(http://coccinelle.lip6.fr/)

<smpl>
@@ struct resource ptr; @@
- (ptr.end - ptr.start + 1)
+ resource_size(&ptr)
</smpl>
