s390/cio: wait_cons_dev don't use static variable
wait_cons_dev is used to busy wait for an interrupt on the console ccw device. Stop using the static console_subchannel and add a parameter to this function to specify on which ccw device/subchannel we have to do the polling. While at it rename the function to ccw_device_wait_idle and move it to device.c Reviewed-by: Peter Oberparleiter <oberpar@linux.vnet.ibm.com> Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
