Above issue happens as follows:

bfad_init error = bfad_im_module_init() fc_release_transport(bfad_im_scsi_transport_template); if (error) goto ext;

ext: bfad_im_module_exit(); fc_release_transport(bfad_im_scsi_transport_template); –> Trigger double release

Don't call bfad_im_module_exit() if bfad_im_module_init() failed.
