uvc_video_get_ts() returns a 'struct timespec', but all its users really want a nanoseconds variable anyway.
Changing the deprecated ktime_get_ts/ktime_get_real_ts to ktime_get and ktime_get_real simplifies the code noticeably, while keeping the resulting numbers unchanged.

As you've done lots of work moving code away from timespec I figured out I would ask, what is the preferred way to print a ktime in secs.nsecs format ? Should I use ktime_to_timespec and print ts.tv_sec and ts.tv_nsec, or is there a better way ?
