From ec64333c3a9bc52e34d79cff23acf4e5764b1353 Mon Sep 17 00:00:00 2001 From: Sebastian Ott Date: Mon, 7 Dec 2009 12:51:36 +0100 Subject: [PATCH] [S390] cio: handle failed disable_subchannel after device recognition Handle a failing cio_disable_subchannel at the end of our device recognition as if the recognition itself failed. This way subsequent registration steps do not need to handle enabled subchannels.
