x86/crash: 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> Signed-off-by: Borislav Petkov <bp@suse.de> Link: https://lkml.kernel.org/r/1577900990-8588-10-git-send-email-Julia.Lawall@inria.fr
