[S390] qdio: fix compile warning under 31 bit
The QEBSM instructions are only available for CONFIG_64BIT, they are not used under 31 bit. Make compiler happy about the false positive: drivers/s390/cio/qdio_main.c: In function ?qdio_inbound_q_done?: drivers/s390/cio/qdio_main.c:532: warning: ?state? may be used uninitialized in this function Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
