call request_irq before or after hardware initialization?

[Li Juen Hwang]

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.
