[RFC PATCH] hw/s390x/ccw: Register qbus type in abstract TYPE_CCW_DEVICE parent |
Date: |
Sat, 24 Apr 2021 16:53:13 +0200 |
Instead of having all TYPE_CCW_DEVICE children set the bus type to
TYPE_VIRTUAL_CSS_BUS, do it once in the abstract parent.
Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org>

RFC because I don't know these devices, maybe there is a reason
for setting the bus type in the children (but it should be documented
IMO).
