fbdev: cg14fb: use resource_size
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> Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr> [b.zolnierkie: minor patch summary fixup] Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Link: https://patchwork.freedesktop.org/patch/msgid/1577900990-8588-8-git-send-email-Julia.Lawall@inria.fr
