patch set submitted to [email protected]:
         [PATCH 0/5] [media] cancel_delayed_work_sync before device removal / 
kfree

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,  a patch set has been submitted to [email protected] 
which contains  fixes for  those modules, too. 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
