MIPS: use resource_size
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> Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Paul Burton <paulburton@kernel.org> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: kernel-janitors@vger.kernel.org Cc: James Hogan <jhogan@kernel.org> Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org
