Subject[PATCH] MIPS: Modify error handling
debugfs_create_file returns NULL on error so an IS_ERR test is
incorrect here and a NULL check is required.

The Coccinelle semantic patch used to make this change is as follows:
@@
expression e;
@@

e = debugfs_create_file(...);
if(
- IS_ERR(e)
+ !e
)
{
<+...
return
- PTR_ERR(e)
+ -ENOMEM
;
...+>
}
