From 4e116e93f4fbd1b5f0e800d312d62d1917370d1a Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 11 Feb 2019 14:48:04 -0800 Subject: Input: db9 - mark expected switch fall-through MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 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/input/joystick/db9.c: In function ‘db9_saturn_read_packet’: drivers/input/joystick/db9.c:256:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (tmp == 0xff) { ^ drivers/input/joystick/db9.c:263:2: note: here default: ^~~~~~~ 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.
