Subject: [PATCH] MIPS: ath79: simplify platform_get_resource_byname/devm_ioremap_resource
|
|
|
|
Remove unneeded error handling on the result of a call to
|
|
platform_get_resource_byname 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,e,e1;
|
|
expression ret != 0;
|
|
identifier l;
|
|
@@
|
|
|
|
res = platform_get_resource_byname(...);
|
|
- if (res == NULL) { ... \(goto l;\|return ret;\) }
|
|
e = devm_ioremap_resource(e1, res);
|
|
// </smpl>
