From 75fc65079d8253e1c25a5f8348111a85d71e0f01 Mon Sep 17 00:00:00 2001 From: Yang Yingliang Date: Sat, 19 Sep 2020 14:35:35 +0800 Subject: tty: hvc: fix link error with CONFIG_SERIAL_CORE_CONSOLE=n aarch64-linux-gnu-ld: drivers/tty/hvc/hvc_dcc.o: in function `dcc_early_write': hvc_dcc.c:(.text+0x164): undefined reference to `uart_console_write' The driver uses the uart_console_write(), but SERIAL_CORE_CONSOLE is not selected, so uart_console_write is not defined, then we get the error. Fix this by selecting SERIAL_CORE_CONSOLE.
