Do you find the following SmPL change specification useful and acceptable?
@deletion depends on patch@
expression e;
@@
e = devm_ioremap_resource(...);
if (IS_ERR(e))
(
-{
- dev_err(...);
return (...);
-}
|{
<+...
- dev_err(...);
...+>
}
)
Would this approach need a version check for the Coccinelle software?
Regards,
Markus
