#3 Make ERROR: implicit declaration of function

[Hua]

I tried to compile HECI-5.0.0.30 under linux kernel 2.6.27.9 but got the following errors:

root@vheci-desktop:/home/vheci/HECI-5.0.0.30# make install

If I replace 'class_device_create' and 'class_device_unregister' with 'device_create' and 'device_unregister', it works. What's the right way to handle it?
