Hi

I write a kmod driver for bh1750 light sensor with iic (almost wrote).
As usual, probe(), attach() and detach(). On attach() it runs 
TIMEOUT_TASK_INIT
for periodically write opecode, read result and place it to sysctl 
dev.bh1750.N
variables. It is all.

But I see that some other devices (from /usr/src/sys/dev) uses 
CONFIG_INTRHOOK(9)
on attach() for initialize themselfs.
I wonder if I need this too? ...or maybe... when I might need it?

Thanks
