Hi I found this problem during randconfig tests for ppc64. drivers/serial/cpm_uart/cpm_uart_core.c: In function 'cpm_put_poll_char': drivers/serial/cpm_uart/cpm_uart_core.c:1002: error: implicit declaration of function 'cpm_uart_early_write' I cannot find any definition nor git-log history for cpm_uart_early_write().
