Not sure why exactly your sparse does not pick it up (too old maybe?)
but the following:
--- linux-2.6.37-rc5/arch/arm/mach-omap1/board-ams-delta.c.orig 2010-12-09 23:07:35.000000000 +0100

@@ -46,81 +46,79 @@ static u16 ams_delta_latch2_reg;
static int ams_delta_keymap[] = {
KEY(0, 0, KEY_F1), /* Advert */
should be
static const unisgned int ams_delta_keymap[] = {
Same goes for the rest of keymaps.
Thanks.
