How is this considered to be a fix and not a workaround?
Set the variable response bit in the control mask and vary the length
based on stfle 140. See __init sclp_early_read_info() in
drivers/s390/char/sclp_early_core.c
Yes it is something to do anyway.
Still in case of error we will need this fix or workaround.
