I reviewed case by case and concluded that each of them is an intentional fall-through. However, it doesn't hurt that the maintainers and supporters of each driver take a look. :) Each commit log contains the particular details for the changes in the corresponding file. This series fix a total of 110 of the following type of warnings in drivers/scsi: drivers/scsi/aic7xxx/aic7xxx_core.c:4921:3: warning: this statement may fall through [-Wimplicit-fallthrough=] ahc_dma_tag_destroy(ahc, scb_data->sg_dmat); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/scsi/aic7xxx/aic7xxx_core.c:4923:2: note: here case 6: ^~~~ Thanks!
