this series is about improving the handling of pointers in struct
zorro_device_id's driver_data.

While it's ok on all current Linux platforms to store a pointer in an
unsigned long variable, it involves casting that loses type information.
This can be nicely seen in patch #7 where after profiting from patch #6
the compiler notices a missing const.

Preparing for that change, all zorro_device_ids are converted to use
named initializers, which is also a nice cleanup that could stand for
itself, as it improves readability for humans. (That is necessary
because an anonymous union can be initialized by name, but not using a
list initializer.)

My motivation for this series is the CHERI hardware extension. With that
pointers are bigger than longs and thus you cannot store pointers in
zorro_device_id::driver_data. So this series is also about getting
support for CHERI into the mainline, but I hope the clean up effects
mentioned above are justification enough to accept this series.

The dependencies in this series are as follows:

  - Patch #5 depends on #1, #2
  - Patches #7 and #8 depend on patch #6.

So if the ata maintainers agreed to merge their patch #1 via scsi, and
Geert agrees to patch #5 and that it's also merged via scsi, patches #1,
#2, #6 and #7 can go in without further coordination.

Patches #3, #4 and #5 are only about using the same initialization style
for all zorro_device_id and can go in without coordination.

Best regards
Uwe

Thanks!

Since it touches various subtrees, I assume you will merge it though your tree?

Well, my plan is that the scsi maintainers pick up patches #1, #2, #6
and #7 and I remind you once #6 (i.e. the dependency for #8) is in
Linus' tree. But with your ack the two fb patches can also go in via
scsi.

To James and Martin: I didn't hear from you about my merge suggestion up
to now. The other affected maintainers agreed so far that (assuming
you're using b4) and interpreting Helge's ack as agreement that you also
pick up the fb patches, you can go for

	b4 am -l -t -3 -P1,2,5-8 cover.1779803053.git.u.kleine-koenig@baylibre.com

If you like I can also pick up these patches (then with your ack please)
and send them to Linus for the next merge window. Just tell me about
your preference.

Best regards
Uwe
