FWIW, I can't seem to figure out how you got mine or Dan's email
addresses as related to this driver.  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?
