From 9842727da7d95d8249087148048cc571f967c023 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Mon, 28 Jul 2008 11:29:56 +1000 Subject: [PATCH] ide/powermac: Fix use of uninitialized pointer on media-bay The current ide-pmac calls media_bay_set_ide_infos() with an uninitialized "hwif" argument. The proper fix is to split the allocation of the hwif from its registration in order to properly setup the mediabay informations before registration.
