3.10-stable review patch. If anyone has any objections, please let me know.
------------------ From: Aruna Balakrishnaiah <[email protected]> commit bf2883339a33b7544b92ea465b90c3de55082032 upstream. pstore_erase is used to erase the record from the persistent store. So if a driver has not defined pstore_erase callback return -EPERM instead of unlinking a file as deleting the file without erasing its record in persistent store will give a wrong impression to customers.
