Subject: [PATCH] [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.
