[S390] cio: remove subchannel init_name
We used the init_name to set the console subchannels name early at the boot stage. With the patch cio: fix memleak in subchannel validation we moved the name setting to the point where we actually register the console subchannel. At this time we can do dynamic allocations and therefore use dev_set_name. Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
