[S390] cio: subchannels in no-path state. (dd9963f9) · Commits · e / devices / android_kernel_oneplus_sm8150

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:
