In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
This patch fixes the following warning:
drivers/isdn/gigaset/ser-gigaset.c: In function ‘gigaset_tty_ioctl’:
drivers/isdn/gigaset/ser-gigaset.c:627:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
switch (arg) {
^~~~~~
drivers/isdn/gigaset/ser-gigaset.c:638:2: 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.
