Sticky module dvb_pll

When I use the latest driver from http://linuxtv.org/hg/v4l-dvb (4d727d223236) and load all the modules I need, as in

/sbin/modprobe firmware_class
/sbin/modprobe i2c-core
/sbin/insmod ./v4l1-compat.ko
/sbin/insmod ./cx24113.ko
/sbin/insmod ./s5h1420.ko
/sbin/insmod ./videobuf-core.ko
/sbin/insmod ./ttpci-eeprom.ko
/sbin/insmod ./cx24123.ko
/sbin/insmod ./saa7146.ko

/sbin/insmod ./budget-core.ko
/sbin/insmod ./budget.ko
/sbin/insmod ./b2c2-flexcop.ko
/sbin/insmod ./b2c2-flexcop-pci.ko

lsmod shows

If immediately after that I do

I get an error when trying to rmmod dvb_pll.
lsmod then shows

Only an explicit

Is this normal behavior, or should dvb_pll be removed with a plain rmmod?

Hm, dvb-pll was some most conflicting stuff, when it came to happen, that all sort of multiple hybrid devices de facto appeared on the markets.

IIRC, Manu suggested just to wait until such is gone, anyway.

It depends on nothing currently, but is still the key to get some same shared "simple" tuners working for analog and digital at once.

This is the best we have so far, not to duplicate tuner code anymore on hybrid devices.

Any closer point, what eventually makes it to be an annoyance to you?
