Subject: 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:
drivers/net/ethernet/rocker/rocker_main.c: In function 'rocker_port_attr_set':
drivers/net/ethernet/rocker/rocker_main.c:2083:9: warning: this statement may fall through [-Wimplicit-fallthrough=]
err = rocker_world_port_attr_pre_bridge_flags_set(rocker_port,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
attr->u.brport_flags,
~~~~~~~~~~~~~~~~~~~~~
trans);
~~~~~~
drivers/net/ethernet/rocker/rocker_main.c:2086:2: note: here
case SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS:
^~~~
Introduced by commit
93700458ff63 ("rocker: Check Handle PORT_PRE_BRIDGE_FLAGS")
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).
