cpm_uart: build failure

[Alexander Beregalov]

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().

Is it really bug from Jul 23 11:30:16 2008?

commit 8e21d04c077c50284bdad10fda8f8cea674458e1
