The solution is more complex, as we need to put the frontend code on a separate driver. Please test the enclosed patch. It should be doing the right thing. PS.: There are some other drivers under dvb-usb with the same trouble... they likely don't handle well device unbind, due to the same reason: drivers/media/usb/dvb-usb/af9005-fe.c drivers/media/usb/dvb-usb/friio-fe.c drivers/media/usb/dvb-usb/cinergyT2-fe.c drivers/media/usb/dvb-usb/vp702x-fe.c drivers/media/usb/dvb-usb/dtt200u-fe.c drivers/media/usb/dvb-usb/vp7045-fe.c Cheers, Mauro [PATCH] [media] gp8psk: Fix DVB frontend attach 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 00000000 c12ba080 00000000 00000000 c103ed6a c1616014 00000001 00006dc6 c1615862 00000454 c109e8a7 c109e8a7 00000009 ffffffff 00000000 f13f6a10 f5f5a600 c103ee33 00000009 00000000 00000000 c109e8a7 f80ca4d0 c109f617 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] Signed-off-by: Mauro Carvalho Chehab Cheers, Mauro --- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html diff --git a/drivers/media/dvb-frontends/Kconfig b/drivers/media/dvb-frontends/Kconfig index 012225587c25..b71b747ee0ba 100644 --- a/drivers/media/dvb-frontends/Kconfig +++ b/drivers/media/dvb-frontends/Kconfig @@ -513,6 +513,11 @@ config DVB_AS102_FE depends on DVB_CORE default DVB_AS102 +config DVB_GP8PSK_FE + tristate + depends on DVB_CORE + default DVB_USB_GP8PSK + comment "DVB-C (cable) frontends" depends on DVB_CORE diff --git a/drivers/media/dvb-frontends/Makefile b/drivers/media/dvb-frontends/Makefile index e90165ad361b..93921a4eaa27 100644 --- a/drivers/media/dvb-frontends/Makefile +++ b/drivers/media/dvb-frontends/Makefile @@ -121,6 +121,7 @@ obj-$(CONFIG_DVB_RTL2832_SDR) += rtl2832_sdr.o obj-$(CONFIG_DVB_M88RS2000) += m88rs2000.o obj-$(CONFIG_DVB_AF9033) += af9033.o obj-$(CONFIG_DVB_AS102_FE) += as102_fe.o +obj-$(CONFIG_DVB_GP8PSK_FE) += gp8psk-fe.o obj-$(CONFIG_DVB_TC90522) += tc90522.o obj-$(CONFIG_DVB_HORUS3A) += horus3a.o obj-$(CONFIG_DVB_ASCOT2E) += ascot2e.o diff --git a/drivers/media/usb/dvb-usb/gp8psk-fe.c b/drivers/media/dvb-frontends/gp8psk-fe.c similarity index 76% rename from drivers/media/usb/dvb-usb/gp8psk-fe.c rename to drivers/media/dvb-frontends/gp8psk-fe.c index db6eb79cde07..3eb89af7cae9 100644 --- a/drivers/media/usb/dvb-usb/gp8psk-fe.c +++ b/drivers/media/dvb-frontends/gp8psk-fe.c @@ -14,37 +14,45 @@ * * see Documentation/dvb/README.dvb-usb for more information */ -#include "gp8psk.h" + +#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt + +#include "gp8psk-fe.h" + +#include "dvb_frontend.h" struct gp8psk_fe_state { struct dvb_frontend fe;
