media: rc: Replace timeval with ktime_t in imon.c
This patch changes the 32-bit time type (timeval) to the 64-bit one (ktime_t), since 32-bit time types will break in the year 2038. I use ktime_t instead of all uses of timeval in imon.c This patch also changes do_gettimeofday() to ktime_get() accordingly, since ktime_get returns a ktime_t, but do_gettimeofday returns a struct timeval, and the other reason is that ktime_get() uses the monotonic clock.
