![]() The DVB binding schema at the DVB core assumes that the frontend is a separate driver. Faling to do that causes OOPS when the module is removed, as it tries to do a symbol_put_addr on an internal symbol, causing craches like: WARNING: CPU: 1 PID: 28102 at kernel/module.c:1108 module_put+0x57/0x70 Modules linked in: dvb_usb_gp8psk(-) dvb_usb dvb_core nvidia_drm(PO) nvidia_modeset(PO) snd_hda_codec_hdmi snd_hda_intel snd_hda_codec snd_hwdep snd_hda_core snd_pcm snd_timer snd soundcore nvidia(PO) [last unloaded: rc_core] CPU: 1 PID: 28102 Comm: rmmod Tainted: P WC O 4.8.4-build.1 #1 Hardware name: MSI MS-7309/MS-7309, BIOS V1.12 02/23/2009 Call Trace: dump_stack+0x44/0x64 __warn+0xfa/0x120 module_put+0x57/0x70 module_put+0x57/0x70 warn_slowpath_null+0x23/0x30 module_put+0x57/0x70 gp8psk_fe_set_frontend+0x460/0x460 [dvb_usb_gp8psk] symbol_put_addr+0x27/0x50 dvb_usb_adapter_frontend_exit+0x3a/0x70 [dvb_usb] From Derek's tests: "Attach bug is fixed, tuning works, module unloads without crashing.
