[S390] cio: subchannels in no-path state.
Subchannel may incorrectly remain in state no-path after channel paths have reappeared. Currently the scan for subchannels which are using a channel path ends at the first occurrence if a full link address was provided by the channel subsystem. The scan needs to continue over all subchannels. Signed-off-by: Peter Oberparleiter <peter.oberparleiter@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
