You're also adding a call to ->irq_clear() in there.

The overall meaning/effect of the patch is heavy:  "I don't know why 
these interrupts are popping up, so I'll whack it with a hammer every 
chance I get, to make them go away."  ;-) ;-)

That's taking the easy way out ;-)  It's a bandaid over whatever the 
-real- problem is.
