Subject: s390x/3270: fix instruction interception handler
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1728cff2abef27aa00bc7e5f6f73c13b7bd256cb;p=qemu.git

s390x/3270: fix instruction interception handler

Commit bab482d7405f ("s390x/css: ccw translation infrastructure")
introduced instruction interception handler for different types of
subchannels. For emulated 3270 devices, we should assign the virtual
subchannel handler to them during device realization process, or 3270
will not work.

Fixes: bab482d7405f ("s390x/css: ccw translation infrastructure")
