From 17de805aa69e594785592f08ea08c85602432bb9 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 1 Apr 2019 17:46:57 +0200 Subject: [PATCH] xen, fbfront: mark expected switch fall-through MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/video/fbdev/xen-fbfront.c: In function ‘xenfb_backend_changed’: drivers/video/fbdev/xen-fbfront.c:678:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (dev->state == XenbusStateClosed) ^ drivers/video/fbdev/xen-fbfront.c:681:2: note: here case XenbusStateClosing: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that, in this particular case, the code comment is modified in accordance with what GCC is expecting to find. This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. Signed-off-by: Gustavo A. R.
