This is definitely a fix for "genirq: Provide generic hwirq allocation
facility", but the changelog doesn't describe what the problem is and the
title that this somehow fixes irq_free_descs() doesn't make any sense.
It's the equivalent of just doing
- irq_free_descs(from, cnt);
+ irq_free_descs(from, i - from);
I'd suggest the patch title be changed to
genirq: Fix memory leak when calling irq_free_hwirqs()
and the changelog state
irq_free_hwirqs() always calls irq_free_descs() with a cnt == 0 which
makes it a no-op since the interrupt count to free is decremented in
itself.
