[PATCH] ppc64: iSeries early printk breakage
The earlier commit 8d9273918635f0301368c01b56c03a6f339e8d51 (Consolidate early console and PPCDBG code) broke iSeries because it caused unregister_console(&udbg_console) to be called unconditionally. iSeries never registers the udbg_console. This just reverts part of the change. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
