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.
