Subject: [alsa-devel] [PATCH 06/10] ASoC: SOF: imx8: use resource_size
Date: Wed,  1 Jan 2020 18:49:46 +0100
Message-ID: <1577900990-8588-7-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>
