Subject[PATCH -next 02/12] serial: earlycon: Emit earlycon name in the OF table
Date
The OF device name of the earlycon is never used because there is no
device; re-purpose the name field to store the earlycon name in
the OF earlycon table. Earlycon will use the table entry to
fixup the console name and index.
