In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: drivers/hwmon/f71882fg.c: In function ‘f71882fg_probe’: drivers/hwmon/f71882fg.c:2457:33: warning: this statement may fall through [-Wimplicit-fallthrough=] data->auto_point_temp_signed = 1; ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~ drivers/hwmon/f71882fg.c:2459:3: note: here case f71889fg: ^~~~ 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.
