Subject: [PATCH] scsi: remove superfluous NULL pointer check from scsi_kill_request()
>From Dan's list:
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.
