linux-next: build warning after merge of the net-next tree

Hi all,
After merging the net-next tree, today's linux-next build (x86_64
allmodconfig) produced this warning:
net/socket.c: In function 'sock_ioctl':
net/socket.c:1173:10: warning: this statement may fall through [-Wimplicit-fallthrough=]
err = sock->ops->gettstamp(sock, argp,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cmd == SIOCGSTAMP_OLD,
~~~~~~~~~~~~~~~~~~~~~~
!IS_ENABLED(CONFIG_64BIT));
~~~~~~~~~~~~~~~~~~~~~~~~~~
net/socket.c:1176:3: note: here
case SIOCGSTAMP_NEW:
^~~~
Introduced by commit
0768e17073dc ("net: socket: implement 64-bit timestamps")
I get this warning because I am building with -Wimplicit-fallthrough
in attempt to catch new additions early. The gcc warning can be turned
off by adding a /* fall through */ comment at the point the fall through
happens (assuming that the fall through is intentional).
