From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>
commit 4580ba4ad2e6b8ddaada3db61d179d4dfac12047 upstream.
Macro iounmap() do nothing, but that results in
unused variable warnings all over the place.
This patch convert it to inline to avoid warning
We will get this warning without this patch
${LINUX}/drivers/thermal/broadcom/ns-thermal.c:78:21: \
warning: unused variable 'ns_thermal' [-Wunused-variable]
struct ns_thermal *ns_thermal = platform_get_drvdata(pdev);
