From: Gustavo A. R. Silva Date: Mon, 11 Feb 2019 22:42:37 +0000 (-0600) Subject: isdn_v110: mark expected switch fall-through X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b67de691f60b471401798498c1bc68e63b00708d;p=linux.git isdn_v110: mark expected switch fall-through 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.
