From b67de691f60b471401798498c1bc68e63b00708d Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 11 Feb 2019 16:42:37 -0600 Subject: [PATCH] isdn_v110: 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 warnings: drivers/isdn/i4l/isdn_v110.c: In function ‘EncodeMatrix’: drivers/isdn/i4l/isdn_v110.c:353:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if (line >= mlen) { ^ drivers/isdn/i4l/isdn_v110.c:358:3: note: here case 128: ^~~~ 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. Silva Signed-off-by: David S.
