[Skyeye-developer] S3C2410(2.6.20-rc4) for Skeyey-1.2

[Anthony Lee]

Hello Dave,

The error messages were caused by net device,
but anyway, the net device still worked.

By removing the part of net from your "skyeye.conf",
the messages would go away.

It seems that the "skyeye-v1/net/dev_net_cs8900a.c" needed to be fixed yet.
