Amitoj Kaur Chawla 33799a6d1a 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
  ;
  ...+>
  }
