drivers/scsi/scsi_lib.c +1365 scsi_kill_request(9) warning: variable derefenced in initializer 'cmd'
drivers/scsi/scsi_lib.c +1365 scsi_kill_request(9) warning: variable derefenced before check 'cmd'
We dereference cmd (and possible OOPS if cmd == NULL) before starting
the request so just remove the superfluous debugging code altogether.
[ bart: the potential NULL pointer dereference was finally fixed in
(much later than mine) commit 03b1470 but my patch is still valid ]
