Ok to call disable_irq before request_irq?

[Timur Tabi]

Is it okay to call disable_irq() before calling request_irq()?  My
device creates lots of spurious interrupts, and so I want the
interrupt enable only when I expect a real interrupt to occur.  It
seems to work, but I just want to make sure it's a proper technique.
