net/dccp/timer.c: use 'u64' instead of 's64' to avoid compiler's warning
'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 Signed-off-by: Chen Gang <gang.chen.5i5j@gmail.com> Signed-off-by: David S.
