If both stop key and delay key are empty, the length of these keys is 0. The subtraction operation will cause the u_int type variable to overflow, will cause illegal memory access in key input loop.

This commit fixes this bug by using int type instead of u_init. Acked-by: Heinrich Schuchardt xypron.glpk@gmx.de

Applied to u-boot/master, thanks!
