The number of interrupts in a domain may be not divisible by the number of interrupts each chip handles. Integer division may truncate the result, thus use DIV_ROUND_UP to count numchips. Seems all users of irq_alloc_domain_generic_chips() in current code do not have this issue. I just found the issue while reading the code.
