So how it comes an interrupt came before
neo_param() in jsm_tty_open was called?
If IRQ is shared we have a special debug feature to test shared IRQs
on freeing IRQ stage (*).
But it doesn't matter, the IRQ handler must survive at any stage after
the action has been listed.
Yes, but IRQ_NONE is returned from the ISR in that case.
The issue the patch is fixing is for a "malicious" device and I am not
sure we want to fix this -- if I can put in a malicious device, I can
use hammer to kill the box too…
