Subject[PATCH v2] s390/sclp_vt220: Fix console name to match device
Date
Console name reported in /proc/consoles:

ttyS1 -W- (EC p ) 4:65

does not match the char device name:

crw--w---- 1 root root 4, 65 May 17 12:18 /dev/ttysclp0

so debian-installer inside a QEMU s390x instance gets confused and fails
to start with the following error:

steal-ctty: No such file or directory
