[PATCH] m68k: Atari - leave out spurious request_irq for Falcon IDE



Hi Geert,

I found I need to have this patch in order to avoid doubly registering the 
ST-DMA interrupt for IDE on Falcon.

The interrupt is registered in stdma_init and the current user of the interrupt 
is set by stdma_get_lock. Without the lock held, no interrupt should be 
delivered anyway, so this patch will make it easier to debug locking problems.
