For si2157, kernel panics in call_timer_fn could be triggered by simply doing an rmmod cx23885 A bisect identified commit 2f1ea29fca781b8e6600f3ece1f2dd98ae276294 as the one introducing those kernel panics. It could be identified that si2157_remove was calling kfree(dev) with possibly still active schedule_delayed_work(dev->stat_work). Below drivers/media/tuners and drivers/media/dvb-frontends this issue could also be identified in the following modules: ts2020 af9013 af9033 rtl2830 Therefore, this patch series also includes the equivalent one-liner fixes for these modules.
