Subject: xen/pvcalls-front: mark expected switch fall-through
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3d8765d4f52a0050343bfa99a1a2aa5ef7d841e5;p=openwrt%2Fstaging%2Fblogic.git

xen/pvcalls-front: 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 placed the "fall through" comment
on its own line, which is what GCC is expecting to find.
