Okay, hope this will be right. Checkout the following patch.

 moxa: Remove #ifdef MODULE completely.

 We can pass "module parameters" on the kernel command
line even when !MODULE. So, #ifdef MODULE becomes
obsolete. Also move the declaration moxa_board_conf at the
start of the function, since we were hit by the following warning.

drivers/char/moxa.c: In function `moxa_init':
drivers/char/moxa.c:1040: warning: ISO C90 forbids mixed declarations and code
