+Subject: mei: don't update offset in write
+
+From: Alexander Usyskin <alexander.usyskin@intel.com>
+
+commit a103af1b64d74853a5e08ca6c86aeb0e5c6ca4f1 upstream.
+
+MEI enables writes of complete messages only
+while read can be performed in parts, hence
+write should not update the file offset to
+not break interleaving partial reads with writes.
