Silva Date: Sun, 15 Oct 2017 18:22:10 +0000 (-0500) Subject: net: dccp: mark expected switch fall-throughs X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=bc28df6e8543d41abfb48d4a4c6d445638d6768c;p=openwrt%2Fstaging%2Fblogic.git net: dccp: mark expected switch fall-throughs In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Notice that for options.c file, I placed the "fall through" comment on its own line, which is what GCC is expecting to find. Signed-off-by: Gustavo A. R. Silva Signed-off-by: David S.
