Peter Oberparleiter 376ae4752e [S390] cio: fix I/O cancel function ... Function ccw_device_cancel_halt_clear may cause an unexpected kernel panic if a clear function is currently active at the subchannel for which it is called. In that case, the iretry counter used to determine the number of retries is never initialized, leading to an immediate failure of the function which results in a kernel panic. Fix this by initializing the iretry counter when the function is first called. Also replace the kernel panic with a return code: a single malfunctioning I/O device should not automatically cause a system-wide kernel panic.
