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/)
