From 358f9a77a668660729e705fde9c3cf69f013aa98 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 25 Mar 2008 12:22:47 +0900 Subject: libata: implement and use ata_noop_irq_clear() ->irq_clear() is used to clear IRQ bit of a SFF controller and isn't useful for drivers which don't use libata SFF HSM implementation. However, it's a required callback and many drivers implement their own noop version as placeholder. This patch implements ata_noop_irq_clear and use it to replace those custom placeholders. Also, SFF drivers which don't support BMDMA don't need to use ata_bmdma_irq_clear(). It becomes noop if BMDMA address isn't initialized. Convert them to use ata_noop_irq_clear().
