Silva" Date: Wed, 23 Jan 2019 01:29:55 -0600 Subject: [PATCH] net: 3c509: mark expected switch fall-throughs In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: drivers/net/ethernet/3com/3c509.c:1265:8: warning: this statement may fall through [-Wimplicit-fallthrough=] drivers/net/ethernet/3com/3c509.c:1271:8: warning: this statement may fall through [-Wimplicit-fallthrough=] Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enabling -Wimplicit-fallthrough.
