Christof Schmitt 22ed130719 [SCSI] zfcp: Fix warnings from smatch ... The smatch tool from http://repo.or.cz/w/smatch.git warns about this: drivers/s390/scsi/zfcp_scsi.c +64 zfcp_scsi_command_fail(5) warn: variable dereferenced before check 'scpnt->device' drivers/s390/scsi/zfcp_scsi.c +64 zfcp_scsi_command_fail(5) warn: variable dereferenced before check 'scpnt->device->host' drivers/s390/scsi/zfcp_scsi.c +93 zfcp_scsi_queuecommand(23) warn: variable dereferenced before check 'unit' Fix the first two warnings by removing the checks for scpnt->device and -> host: As long as the SCSI command exists, there is also a scsi_device and a Scsi_Host. Fix the last warning by removing the BUG_ON checks in zfcp_scsi_queuecommand, they are leftovers from previous paranoia about wrong pointers between data structures.
