2018-09-12media: dvb: move compat handlers into driversArnd Bergmann
The VIDEO_STILLPICTURE is only implemented by one driver, while VIDEO_GET_EVENT has two users in tree. In both cases, it is fairly easy to handle the compat ioctls in the native handler rather than relying on translation in fs/compat_ioctls. In effect, this means that now the drivers implement both structure layouts in both native and compat mode, but I don't see anything wrong with that.

2018-09-12media: dvb: move most compat_ioctl handling into driversArnd Bergmann
Most DVB audio and video ioctl commands are completely compatible, and are implemented by just two drivers: ttpci and ivtv. In both cases, we can use the same ioctl handler for both native and compat ioctl handling, and remove the entries from the global lookup table. In case of ttpci, this directly hooks into the file_operations structure, and for ivtv, we have to set the compat_ioctl32 method in v4l2_file_operations. For all I can tell, setting it to video_ioctl2 will still do the right thing for all commands. Note that for the VIDEO_STILLPICTURE and VIDEO_GET_EVENT commands, a translation handler in fs/compat_ioctl.c is still used. This works because the command numbers are different on 32-bit systems.

2018-09-12media: dvb: fix compat ioctl translationArnd Bergmann
The VIDEO_GET_EVENT and VIDEO_STILLPICTURE was added back in 2005 but it never worked because the command number is wrong. Using the right command number means we have a better chance of them actually doing the right thing, though clearly nobody has ever tried it successfully. I noticed these while auditing the remaining users of compat_time_t for y2038 bugs. This one is fine in that regard, it just never did anything.

In this specific case, the code for DVB-S applies for DVB-S2. In a matter of fact, several things there (like rolloff factor logic) assume that the transponder is DVB-S2.

As we only have two fields at the moment this isn't much of an issue, but it prevents easy addition of new info fields. Fix this by storing the uvc_device_info pointer in the uvc_device structure. As a result the uvc_device meta_format field can be removed. The quirks field, however, needs to stay as it can be modified through a module parameter. As not all device have an information structure, we declare a global "NULL" info instance that is used as a fallback when the driver_info is empty.
