[PATCH] netfilter: ebtables: clean up initialization of buf

From: Colin King <hidden>
Date: 2017-10-16 10:24:17
Also in: bridge, kernel-janitors, lkml, netfilter-devel
Subsystem: ethernet bridge, networking [general], the rest · Maintainers: Nikolay Aleksandrov, Ido Schimmel, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

From: Colin Ian King <redacted>

buf is initialized to buf_start and then set on the next statement
to buf_start + offsets[i].  Clean this up to just initialize buf
to buf_start + offsets[i] to clean up the clang build warning:
"Value stored to 'buf' during its initialization is never read"
