Since eisacount and pcicount is doing the same task (and they are only
used in sequence) and to preventing more #ifdef in the source-code, why
not use the same variable? It will give an warning if both of them is
not defined, but is that an issue? If so,
#if !defined CONFIG_EISA && !defined CONFIG_PCI
could encapsulate the variable to prevent that.
Posted 26'th of October and now also checked against 2.6.14-git1.

Well, both of them do the same stuff, but one of these patches needs
to be committed.

Can both CONFIG_PCI and CONFIG_EISA be undefined at the same time? If
so, I think you patch is better.
But on line 1015 in the dgrs.c-file (function dgrs_download()) there is
an if-statement:
if (priv0->plxreg)
{ /* PCI bus */
...
}
else
{ /* EISA bus */
...
from where I got the idea it needs either pci or eisa (or both). If this
is true, I vote for my patch.
Live long and prosper

PS
Rick's mail-address in the file seems invalid. Changed it to
netdev@vger.kernel.org, since that is the address in the MAINTAINERS-file.

Both CONFIG_PCI and CONFIG_EISA cant be undefined at the same time,
because the device has to be on either of the 2 busses. I think your
patch is better in that case.

Not for this driver. From drivers/net/dgrs.c:
config DGRS
tristate "Digi Intl. RightSwitch SE-X support"
depends on NET_PCI && (PCI || EISA)

Let's go with Ashutosh's patch then, thanks.

In fact we can de-ifdef things a bit.

Acked. The above patch does the trick too. Any one can be committed.

I do not know what to think about this one:
* reduce one #ifdef: good
* check for something clearly stated not to: not so good
But as Ashutosh Naik said: Any one can be committed.

Well a nicer fix would be to provide a stub implementation of
eisa_driver_register() if !CONFIG_EISA, just like pci_register_driver().
Then all the ifdefs go away and the compiler removes all the code for us,
after checking that we typed it correctly.

Oh, sorry. Missed the stub implementation of the pci-driver. I "ack"
your patch.
BTW, can anyone ack or is that up to the maintainers?
BTW #2, why not remove #ifdef CONFIG_PCI on dgrs_cleanup_module() at the
same time? Or maybe that should be in a "remove config_pci"-patch...

Just realized; what happens if CONFIG_EISA && !CONFIG_PCI and
eisa_driver_register() returns value > 0, then the if-statement for the
pci-driver is going to return the value, instead of 0.

if !CONFIG_PCI, pci_register_driver() will return zero.

It's useful info - it shows that someone else took the time to revie the
code.

yup. There are lots of opportunities for that, I bet.
