Hello
Those timers are activated on frontend init() ja de-activated on
sleep(). Removing active driver does not sound good and IMHO it should
not be even possible. I think it should be find out why it is possible
to remove whole driver before it is put to sleep().

Hi again,
seems that the cause for the kernel panic is a missing call to
cancel_delayed_work_sync in si2157_remove before the call to kfree.
After adding cancel_delayed_work_sync(&dev->stat_work), rmmod does not
trigger the kernel panic any more.
However, very similar issues could be identified also in other modules:
ts2020
af9013
af9033
rtl2830
when looking in drivers/media/tuners and drivers/media/dvb-frontends.
Therefore, the submitted patch set contains fixes also for those
modules. The submitted patch set is:
[PATCH 0/5] [media] cancel_delayed_work_sync before device removal / kfree
I hope these patches completely fix the issue and are ok for inclusion
in the kernel.
BR and thx,
Martin
