2008-12-25[S390] qdio: fix compile warning under 31 bitJan Glauber1-1/+1
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>
2008-08-21[S390] qdio: prevent oopsing if qdio_establish failsJan Glauber1-1/+5
If qdio_establish fails we call qdio_shutdown to cleanup the qdio subchannel. The tiq_list entry may not be valid at that time, therefore we must ignore queues with an invalid list entry in tiqdio_remove_input_queues.
