Subject[PATCH -next 10/12] of: earlycon: Log more helpful message if earlycon not found
Date
Earlycon may fail to initialize for a variety of reasons, most of
which log the default early param message. If the earlycon is
not found, log the OF path which was not found (and suppress the
default early param message).
