that is our -v2 version.
YH
Subject: [PATCH -v2.1 2/2] genericirq: change ack/mask in irq_chip to take irq_desc instead of irq
will have
void (*ack)(struct irq_desc *desc);
void (*mask)(struct irq_desc *desc);
void (*mask_ack)(struct irq_desc *desc);
void (*unmask)(struct irq_desc *desc);
void (*eoi)(struct irq_desc *desc);
so for sparseirq with raidix tree, we don't call extra irq_to_desc, and could use desc directly
-v2: change all member of irq_chip to use desc only.
-v2.1: update after legacy_pic
