From 150981b0306fc5773b929e31ab5b0590c87cc77c Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Tue, 23 Oct 2007 16:50:02 +0100 Subject: [PATCH] libata-core: auditting chk_status v check_status Did a complete audit of these and found we have another error case. ata_bus_softreset calls ata_check_status which means that it tries to do an ioread8 on the port blindly and check versus 0xFF for an error. It should of course be using the ap->ops method for this via chk_status, and this bug causes a wrog status call on the NS87415 at least.
