From 0c3812c347bfb0dc213556a195e79850c55702f5 Mon Sep 17 00:00:00 2001 From: Vineeth Vijayan Date: Fri, 17 Sep 2021 15:04:01 +0200 Subject: s390/cio: derive cdev information only for IO-subchannels cdev->online for the purge function must not be checked for the non-IO subchannel type. Make sure that we are deriving the cdev only from sch-type SUBCHANNEL_TYPE_IO.
