I found I need to have this patch in order to avoid doubly registering the ST-DMA interrupt for IDE on Falcon.
But further it has no ill effects, as it works fine on ARAnyM? Or does it fail on real hardware?
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.

Ugh, adding an m68k dependency in generic code is not nice... Would it work to add a generic test for hwif->irq, and set hwif->irq to zero in falconide.c?
