    Subject[PATCH 5.4 129/408] tty: serial: earlycon dependency
    Date
    From: Tong Zhang <ztong0001@gmail.com>

    [ Upstream commit 0fb9342d06b0f667b915ba58bfefc030e534a218 ]

    parse_options() in drivers/tty/serial/earlycon.c calls uart_parse_earlycon
    in drivers/tty/serial/serial_core.c therefore selecting SERIAL_EARLYCON
    should automatically select SERIAL_CORE, otherwise will result in symbol
    not found error during linking if SERIAL_CORE is not configured as builtin

    Fixes: 9aac5887595b ("tty/serial: add generic serial earlycon")
