'dccp_timestamp_seed' is initialized once by ktime_get_real() in
dccp_timestamping_init(). It is always less than ktime_get_real()
in dccp_timestamp().
Then, ktime_us_delta() in dccp_timestamp() will always return positive
number. So can use manual type cast to let compiler and do_div() know
about it to avoid warning.
The related warning (with allmodconfig under unicore32):
CC [M] net/dccp/timer.o
net/dccp/timer.c: In function ‘dccp_timestamp’:
net/dccp/timer.c:285: warning: comparison of distinct pointer types lacks a cast
