We have a number of Android TV-based products currently running on the 4.9 kernel and this was broken for them. Thanks to Robert McConnell for identifying and providing the patches in their initial format. In order for Jaedon's patches to apply cleanly a number of changes were applied to support those changes. If you deem the patch series too big please let me know. Thanks Colin Ian King (2): media: dvb_frontend: ensure that inital front end status initialized media: dvb_frontend: initialize variable s with FE_NONE instead of 0 Jaedon Shin (3): media: dvb_frontend: Add unlocked_ioctl in dvb_frontend.c media: dvb_frontend: Add compat_ioctl callback media: dvb_frontend: Add commands implementation for compat ioct Katsuhiro Suzuki (1): media: dvb_frontend: fix wrong cast in compat_ioctl Mauro Carvalho Chehab (14): media: dvb/frontend.h: move out a private internal structure media: dvb/frontend.h: document the uAPI file media: dvb_frontend: get rid of get_property() callback media: stv0288: get rid of set_property boilerplate media: stv6110: get rid of a srate dead code media: friio-fe: get rid of set_property() media: dvb_frontend: get rid of set_property() callback media: dvb_frontend: cleanup dvb_frontend_ioctl_properties() media: dvb_frontend: cleanup ioctl handling logic media: dvb_frontend: get rid of property cache's state media: dvb_frontend: better document the -EPERM condition media: dvb_frontend: fix return values for FE_SET_PROPERTY media: dvb_frontend: be sure to init dvb_frontend_handle_ioctl() return code media: dvb_frontend: fix return error code Satendra Singh Thakur (1): media: dvb_frontend: dtv_property_process_set() cleanups .../media/uapi/dvb/fe-get-property.rst | 7 +- drivers/media/dvb-core/dvb_frontend.c | 571 +++++++++++------ drivers/media/dvb-core/dvb_frontend.h | 13 - drivers/media/dvb-frontends/lg2160.c | 14 - drivers/media/dvb-frontends/stv0288.c | 7 - drivers/media/dvb-frontends/stv6110.c | 9 - drivers/media/usb/dvb-usb/friio-fe.c | 24 - fs/compat_ioctl.c | 17 - include/uapi/linux/dvb/frontend.h | 592 +++++++++++++++--- 9 files changed, 881 insertions(+), 373 deletions(-) Reviewed-by: Sean Young
