Which kernel version are you using ?

AFAIK, in 2.4.x, one had to call MOD_INC_USE_COUNT in the open() method
of the character driver. But in 2.6.x, I think this is done
automagically. Isn't it ?

Maybe you should have a look at Linux Device Drivers, the 3rd edition is
available online.

Sincerly,

Thomas
