From 1fc142589e58b20a67582974b8848595a2c7432e Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Mon, 28 Apr 2008 23:44:39 +0200 Subject: [PATCH] ide: add ide_execute_pkt_cmd() helper Add ide_execute_pkt_cmd() helper for executing PACKET command, then convert ATAPI device drivers to use it. As a nice side-effect this fixes ide-{floppy,tape,scsi} w.r.t. ide_lock taking (ide-cd was OK).
