Calling i2c_unregister_device for a demod driver destroys the frontend object. Later it is accessed by calling dvb_unregister_frontend and dvb_frontend_detach. In some cases this leads to a general protection fault with this callstack: dvb_unregister_frontend+0x25/0x50 [dvb_core] dvb_fini+0xdb/0x160 [cx231xx_dvb] cx231xx_unregister_extension+0x3d/0xb0 [cx231xx] cx231xx_dvb_unregister+0x10/0x809 [cx231xx_dvb] SyS_delete_module+0x18a/0x240 ? exit_to_usermode_loop+0x7b/0x80 entry_SYSCALL_64_fastpath+0x17/0x98 Signed-off-by: Matthias Schwarzott <zzam@gentoo.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> |
