After getting warnings in an allyesconfig build[1] from this
driver, I decided to remind myself just how old it was, and
whether it warranted fixing. In the Kconfig help text, I found:
"This driver will eventually be phased out entirely"
Going back to the history archive, I see the line was added[2]
in Feb 2002, when we moved from v2.4.2.1 ---> v2.4.2.2
So, with over a decade of notification, and multiple major releases
since then, I think we can justify removing this. Currently we have
people wasting time building it during routine testing, and then
wasting more time re-researching the known reported warnings, only to
find that nobody really is willing to integrate the fixes[3] for it.
A quick search didn't seem to indicate any active user base for it.
If someone happens to have a quirky _old_ card that the eleven year
old "new" driver doesn't work with, then it is entirely reasonable
that they stick with a kernel version that predates this removal.

- tristate "Adaptec AIC7xxx support (old driver)"
- depends on (ISA || EISA || PCI ) && SCSI
- help
- WARNING This driver is an older aic7xxx driver and is no longer
- under active development. Adaptec, Inc. is writing a new driver to
- take the place of this one, and it is recommended that whenever
- possible, people should use the new Adaptec written driver instead
- of this one. This driver will eventually be phased out entirely.
-
- This is support for the various aic7xxx based Adaptec SCSI
- controllers. These include the 274x EISA cards; 284x VLB cards;
- 2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
- motherboard based SCSI controllers from Adaptec. It does not support
- the AAA-13x RAID controllers from Adaptec, nor will it likely ever
- support them. It does not support the 2920 cards from Adaptec that
- use the Future Domain SCSI controller chip. For those cards, you
- need the "Future Domain 16xx SCSI support" driver.
-
- In general, if the controller is based on an Adaptec SCSI controller
- chip from the aic777x series or the aic78xx series, this driver
- should work. The only exception is the 7810 which is specifically
- not supported (that's the RAID controller chip on the AAA-13x
- cards).
-
- Note that the AHA2920 SCSI host adapter is *not* supported by this
- driver; choose "Future Domain 16xx SCSI support" instead if you have
- one of those.
-
- Information on the configuration options for this controller can be
- found by checking the help file for each of the available
- configuration options. You should read
- <file:Documentation/scsi/aic7xxx_old.txt> at a minimum before
- contacting the maintainer with any questions. The SCSI-HOWTO,
- available from <http://www.tldp.org/docs.html#howto>, can also
- be of great help.
-
- To compile this driver as a module, choose M here: the
- module will be called aic7xxx_old.
