From 3b36f66b81bc0d69ec7dfa736592224f6ca366b7 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Sat, 26 Apr 2008 22:25:16 +0200 Subject: [PATCH] ide: add ide_legacy_device_add() helper Add ide_legacy_device_add() helper for use by legacy VLB host drivers (+ convert them to use it). There should be no functional changes caused by this patch.
