Hi guys,

U are right. U can have two or more than that irq in a
device driver. Let' say if u have

request_irq(irq no(17), handle1.....)
request_irq(irq no(18), handle2.....)
For os it does not matter from where u have
So whenever interrupt 17 will occur handle1 will be
in another case handle2......

So u can always do that...i guess so

Deep into Silicon with linux...
