Okay, point taken :) So for cases of base == maxbase, why would we ever
want to return a nonzero value? What is the intended purpose of the
second part of that conditional?

Can anyone lend an explanation of the following?
/* base == maxbase can be valid only if the BAR has
already been programmed with all 1s. */
if (base == maxbase && ((base | size) & mask) != mask) {
printk("%s: 2 returning 0\n", __FUNCTION__);
