Silva Date: Tue, 17 Oct 2017 22:42:53 +0000 (-0500) Subject: net: l2tp: mark expected switch fall-through X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=be070c77ca805a4f06f135599415195078f0ed68;p=linux.git net: l2tp: mark expected switch fall-through In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Notice that in this particular case I replaced the "NOBREAK" comment with a "fall through" comment, which is what GCC is expecting to find. Signed-off-by: Gustavo A. R.
