CCW group devices are devices that use multiple subchannels on the mainframe's
channel subsystem. A qeth group device maps to subchannels and their
corresponding device numbers and device bus-IDs.
The qeth device driver requires three I/O subchannels for each HiperSockets
CHPID or OSA-Express CHPID in QDIO mode. One subchannel is for control reads,
one for control writes, and the third is for data.
The qeth device driver uses the QDIO protocol to communicate with the
HiperSockets and OSA-Express adapter.
As the node device driver is building a tree relationship between nodes the
ccwgroup device is placed besides the subchannel nodes under computer and list
the group members within a new ccwgroup capability. A new capability
ccwgroup_member is added into capability ccw to represent a device membership
to a ccwgroup. Filters are added to find ccwgroups as well as ccwgroup members.

Apart from the broken build where clang complains about assignment to
the unsigned enum which I've fixed, this doesn't report an error ...
Peter, thanks for fixing the clang problem.
I agree that here I should add reporting an internal error as this
should not happen since the devtype was already used before in the udev
event handling to get here and not being able to do the conversion would
be an error. I will send a patch shortly.

... and neither this at least on 2 code paths:
1) the dummy impl if not running on linux
2) if the assertion that a group must be non-empty fails in the real
code path inside virCCWGroupDeviceGetMembers.
This is implemented following the common DynamicCaps pattern, e.g. as in
virNodeDeviceGetMdevParentDynamicCaps.
Therefore I would refrain from adding error reporting.
The caller does seem to care about errors as other code paths do set
them, thus this should as well.

CCW group devices are devices that use multiple subchannels on the
mainframe's
channel subsystem. A qeth group device maps to subchannels and their
corresponding device numbers and device bus-IDs.
The qeth device driver requires three I/O subchannels for each HiperSockets
CHPID or OSA-Express CHPID in QDIO mode. One subchannel is for control reads,
one for control writes, and the third is for data.
The qeth device driver uses the QDIO protocol to communicate with the
HiperSockets and OSA-Express adapter.
As the node device driver is building a tree relationship between nodes the
ccwgroup device is placed besides the subchannel nodes under computer and list
the group members within a new ccwgroup capability. A new capability
ccwgroup_member is added into capability ccw to represent a device membership
to a ccwgroup. Filters are added to find ccwgroups as well as ccwgroup members.

I'll fix that before merging.
