Subject: Compiler warnings in kernel 4.14.51

Hello!

While compiling kernel 4.14.51 I got the following warnings:
CC      net/core/dev.o
net/core/dev.c: In function 'validate_xmit_skb_list':
net/core/dev.c:3121:15: warning: 'tail' may be used uninitialized in this function [-Wmaybe-uninitialized]
...

CC      net/ipv4/fib_trie.o
net/ipv4/fib_trie.c: In function 'fib_trie_unmerge':
net/ipv4/fib_trie.c:1749:8: warning: 'local_tp' may be used uninitialized in this function [-Wmaybe-uninitialized]

The kernel has been compiled for the MIPS architecture, little-endian 32-bit.
My /prov/version file content is:
Linux version 4.14.51 (mrkiko@...ation) (gcc version 7.3.0 (OpenWrt GCC 7.3.0 r7360-e15565a01c)) #0 Fri Jun 29 05:54:17 2018

thank you very much to all of you for your great work.

Enrico
