From d816d4238245b019d6f86f58163c78f015bd94ed Mon Sep 17 00:00:00 2001 From: Klaus-Dieter Wacker Date: Wed, 14 Oct 2009 22:54:58 +0000 Subject: [PATCH] lcs: Recognize return codes of ccw_device_set_online(). The creation of a new lcs device requires a call to the function ccw_device_set_online() for the read and the write channel. Failure of either call should terminate the lcs device creation immediately with return code -ENODEV. Signed-off-by: Klaus-Dieter Wacker Signed-off-by: Ursula Braun Signed-off-by: David S.
