mptcp: fix format specifiers for unsigned int
Some of the sequence numbers are printed as the negative ones in the debug log: [ 46.250932] MPTCP: DSS [ 46.250940] MPTCP: data_fin=0 dsn64=0 use_map=0 ack64=1 use_ack=1 [ 46.250948] MPTCP: data_ack=2344892449471675613 [ 46.251012] MPTCP: msk=000000006e157e3f status=10 [ 46.251023] MPTCP: msk=000000006e157e3f snd_data_fin_enable=0 pending=0 snd_nxt=2344892449471700189 write_seq=2344892449471700189 [ 46.251343] MPTCP: msk=00000000ec44a129 ssk=00000000f7abd481 sending dfrag at seq=-1658937016627538668 len=100 already sent=0 [ 46.251360] MPTCP: data_seq=16787807057082012948 subflow_seq=1 data_len=100 dsn64=1 This patch used the format specifier %u instead of %d for the unsigned int values to fix it.
