Hi,
I can not get my com20020 pcmcia driver to work as a module under 2.6.20.
There is the build problem:
MODPOST 30 modules
WARNING: "com20020_found" [drivers/net/pcmcia/com20020_cs.ko] undefined!
WARNING: "com20020_check" [drivers/net/pcmcia/com20020_cs.ko] undefined!
The solution:
Always export com20020_found and com20020_check.
Esben

The relevant parts:
...
CONFIG_ARCNET_COM20020=m
# CONFIG_ARCNET_COM20020_ISA is not set
# CONFIG_ARCNET_COM20020_PCI is not set
...
CONFIG_ARCNET_COM20020_CS=m
In this hiracy it is not nice for the com20020 module to check wether
there are users for it. It breaks the direction of dependency. What if I
first compile com20020 install it, and then decide I want one of the other
modules? Then would I have to recompile com20020 and reload it.
Therefore: Remove the check, do always export the symbols.
As for actually testing: I have access to ArcNet hardware for 3 more
weeks. Then I will start at a new job, where there is no ArcNet.

Sorry about that.

That's not the usual kernel way, but I'll leave it up to the netdev
people. (and net mailing list changed from linux-net to netdev)
An alternative patch is below.
Thanks for your report and patch.

Need to export com20020 symbols for com20020_cs also.
