The MAINTAINERS file only lists Hannes. The driver Dan and I worked on was a different driver. It was named aic7xxx, but that was back in the 1990s. It was renamed to aic7xxx_old so that Adaptec could contribute this driver you are currently patching back around 2001 or so. And then maybe around 2010 or something like that, the aic7xxx_old driver that Dan and I worked on was removed from the upstream source tree entirely. So, just out of curiosity, how did you get mine and Dan's email addresses to put on the Cc: list for these patches? > Signed-off-by: Lee Jones <lee.jones@linaro.org> > --- > drivers/scsi/aic7xxx/aic7xxx_osm.c | 5 ----- > 1 file changed, 5 deletions(-) > > diff --git a/drivers/scsi/aic7xxx/aic7xxx_osm.c > b/drivers/scsi/aic7xxx/aic7xxx_osm.c > index 2edfa0594f183..32bfe20d79cc1 100644 > --- a/drivers/scsi/aic7xxx/aic7xxx_osm.c > +++ b/drivers/scsi/aic7xxx/aic7xxx_osm.c > @@ -564,8 +564,6 @@ ahc_linux_target_alloc(struct scsi_target > *starget) > struct scsi_target **ahc_targp = > ahc_linux_target_in_softc(starget); > unsigned short scsirate; > struct ahc_devinfo devinfo; > - struct ahc_initiator_tinfo *tinfo; > - struct ahc_tmode_tstate *tstate; > char channel = starget->channel + 'A'; > unsigned int our_id = ahc->our_id; > unsigned int target_offset; > @@ -612,9 +610,6 @@ ahc_linux_target_alloc(struct scsi_target > *starget) > spi_max_offset(starget) = 0; > spi_min_period(starget) = > ahc_find_period(ahc, scsirate, maxsync); > - > - tinfo = ahc_fetch_transinfo(ahc, channel, ahc->our_id, > - starget->id, &tstate); > } > ahc_compile_devinfo(&devinfo, our_id, starget->id, > CAM_LUN_WILDCARD, channel,
