Hello Krishna Gudipati,
This is a semi-automatic email about new static checker warnings.
The patch 5b7db7af522d: "[SCSI] bfa: Implement LUN Masking feature
using the SCSI Slave Callouts." from Dec 20, 2011, leads to the
following Smatch complaint:
drivers/scsi/bfa/bfad_im.c +962 bfad_im_slave_alloc()
warn: variable dereferenced before check 'rport' (see line 959)
drivers/scsi/bfa/bfad_im.c
957 struct fc_rport *rport = starget_to_rport(scsi_target(sdev));
958 struct bfad_itnim_data_s *itnim_data =
959 (struct bfad_itnim_data_s *) rport->dd_data;
^^^^^^^
New dereference.
960 struct bfa_s *bfa = itnim_data->itnim->bfa_itnim->bfa;
961
962 if (!rport || fc_remote_port_chkready(rport))
^^^^^
Old check.
963 return -ENXIO;
964
regards,
dan carpenter
