[PATCH 2/7] [media] dvb: remove unused systime() function

Show all headers | View raw

The systime function uses struct timespec, which we want to stop
using in the kernel because it overflows in 2038. Fortunately,
this use in dibx000_common is in a function that is never called,
so we can just remove it.
