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.
