[PATCH 03/10] fbdev: s1d13xxxfb: use resource_size
From: Julia Lawall <Julia.Lawall@inria.fr>

Subsystem:
epson s1d13xxx framebuffer driver, framebuffer layer, the rest · Maintainers:

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)
