cpuidle-kirkwood.c: simplify use of devm_ioremap_resource()
Remove unneeded error handling on the result of a call to
platform_get_resource when the value is passed to
devm_ioremap_resource().
A simplified version of the semantic patch that makes this change is
as follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
expression pdev,res,n,e,e1;
expression ret != 0;
identifier l;
@@
- res = platform_get_resource(pdev, IORESOURCE_MEM, n);
... when != res
- if (res == NULL) { ... \(goto l;\|return ret;\) }
... when != res
+ res = platform_get_resource(pdev, IORESOURCE_MEM, n);
e = devm_ioremap_resource(e1, res);
// </smpl>
