From cb57f2eb0156829f61dd946d96b1270ea7535b76 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 11 Feb 2019 16:23:18 -0600 Subject: [PATCH] iio: mma8452: 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/iio/accel/mma8452.c: In function ‘mma8452_probe’: drivers/iio/accel/mma8452.c:1581:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (ret == data->chip_info->chip_id) ^ drivers/iio/accel/mma8452.c:1584:2: note: here default: ^~~~~~~ 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.
