Subject: [PATCH 00/41] scsi: Mark expected switch fall-throughs
Message-ID: <cover.1543374820.git.gustavo@embeddedor.com>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii

In preparation to enabling -Wimplicit-fallthrough, this patchset aims
to mark switch cases where we are expecting to fall through.

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!
