Subject[PATCH 62/62] Blackfin: fix sparseirq/kstat_irqs fallout
Date
The sparseirq changes (d7e51e66) played poorly with the Blackfin irqchip
implementation as we're still using the old hardirq method. Our bad irq
structure had a NULL kstat_irqs field so when all the common code tries
to increment this field, everything goes big bada boom.
