isdn: i4l: isdn_tty: 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_tty.c: In function ‘isdn_tty_edit_at’: drivers/isdn/i4l/isdn_tty.c:3644:18: warning: this statement may fall through [-Wimplicit-fallthrough=] m->mdmcmdl = 0; ~~~~~~~~~~~^~~ drivers/isdn/i4l/isdn_tty.c:3646:5: note: here case 0: ^~~~ 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 <gustavo@embeddedor.com> Signed-off-by: David S. Miller <davem@davemloft.net>
