From aa2731ad9ad80ac3fca48bd1c4cf0eceede4810e Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 7 Apr 2008 22:47:19 +0900 Subject: libata: separate out ata_wait_ready() and implement ata_wait_after_reset() Factor out waiting logic (which is common to all ATA controllers) from ata_sff_wait_ready() into ata_wait_ready(). ata_wait_ready() takes @check_ready function pointer and uses it to poll for readiness. This allows non-SFF controllers to use ata_wait_ready() to wait for link readiness. This patch also implements ata_wait_after_reset() - generic version of ata_sff_wait_after_reset() - using ata_wait_ready(). ata_sff_wait_ready() is reimplemented using ata_wait_ready() and ata_sff_check_ready(). Functionality remains the same.
