[PATCH 3/7] pstore: Warn for the case of PSTORE_TYPE_PMSG write using deprecated function

From: Joel Fernandes
Date: Thu Oct 20 2016 - 03:18:14 EST


PMSG now uses ramoops_pstore_write_buf_user instead of ramoops_pstore_write_buf
Print a ratelimited warning if the ramoops_pstore_write_buf is called.
