linux-toradex.git/include/uapi/linux/dvb/video.h, branch v4.14-rc7 Linux kernel for Apalis and Colibri modules [media] dvb: don't use 'time_t' in event ioctl 2017-06-20T14:27:01+00:00 Arnd Bergmann arnd@arndb.de 2015-09-17T21:19:34+00:00 d320695add65d8f909e4edbdcc8b66ae504854a6 'struct video_event' is used for the VIDEO_GET_EVENT ioctl, implemented by drivers/media/pci/ivtv/ivtv-ioctl.c and drivers/media/pci/ttpci/av7110_av.c. The structure contains a 'time_t', which will be redefined in the future to be 64-bit wide, causing an incompatible ABI change for this ioctl. As it turns out, neither of the drivers currently sets the timestamp field, and it is presumably useless anyway because of the limited resolutions (no sub-second times). This means we can simply change the structure definition to use a 'long' instead of 'time_t' and remain compatible with all existing user space binaries when time_t gets changed. If anybody ever starts using this field, they have to make sure not to use 1970 based seconds in there, as those overflow in 2038.

[media] fix broken references on dvb/video*rst 2016-09-09T12:53:35+00:00 Mauro Carvalho Chehab mchehab@s-opensource.com 2016-08-31T19:34:07+00:00 848d10314bfe1be79f5ca4deb3d2bf81f6adcf38 Trivially fix those broken references, by copying the structs fron the header, just like other API documentation at the DVB side. This doesn't have the level of quality used at the V4L2 side of the API, but, as this documents a deprecated API, used only by av7110 driver, it doesn't make much sense to invest time making it better.
