call request_irq before or after hardware initialization?

Hi, Most 1394 drivers on Linux, ohci1394 for instance, calls request_irq() before initializing/enabling hardware chip. I'd like to reverse the order so that driver can exit the kernel without calling free_irq() if hardware failed. Is that ok? will it cause side effect? Thanks.
