Just a thought:
The client concept is really specific to s390 platform firmware ISM.
So wouldn't it be nice to do something like:
diff --git a/drivers/s390/net/ism_drv.c b/drivers/s390/net/ism_drv.c
index 78cca4839a31..37dcdf2bc044 100644

This is not a real patch, just a sketch, but I hope you
get the idea.
This may be a step in the direction of moving the ism_client concept from
net/smc/smc_ism.c to drivers/s390/net/ism*
I know that there are several dependencies to consider.
And I haven't looked at the other patches in this series yet in detail, to see how you solve
things like smcd_register_dev. Seems like smcd_register_dmb() is the only one of the smcd_ops
that you need for loopback and uses ism_client.
Wenjia, Gerd, and others what do you think?
