[PATCH] pstore: Add prefix to ECC messages

[Vincent Whitchurch]

The "No errors detected" message from the ECC code is shown at the end
of the pstore log and can be confusing or misleading, especially since
it usually appears just after a kernel crash log which normally means
quite the opposite of "no errors".  Prefix the message to clarify that
this message is only about ECC-detected errors.
