Summary:                    Cannot unload wct4xxp zaptel kernel module
Description: 
I cannot unload a unused wct4xxp zaptel kernel module. Every time I try to
remove it I get a kernel oops/crash.

1. boot-up the system
2. load zaptel module (modprobe zaptel)
3. load wct4xxp module (modprobe wct4xxp)
4. unload wct4xxp module (rmmod wct4xxp) <<--- it says that it's in use
and crash!
5. unload zaptel module (rmmod zaptel)   <<--- I can't get here since 4
failed
