From 6762511934e6e7287ce3c8baac0d52ef64e3787b Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Tue, 31 Mar 2009 20:15:30 +0200 Subject: ide: rename IDE_TFLAG_IN_[HOB_]FEATURE The feature register has never been readable -- when its location is read, one gets the error register value; hence rename IDE_TFLAG_IN_[HOB_]FEATURE into IDE_TFLAG_IN_[HOB_]ERROR and introduce the 'hob_error' field into the 'struct ide_taskfile' (despite the error register not really depending on the HOB bit).
