virt: vbox: 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 warning:
drivers/virt/vboxguest/vboxguest_core.c: In function ‘vbg_core_ioctl’:
drivers/virt/vboxguest/vboxguest_core.c:1486:10: warning: this statement may fall through [-Wimplicit-fallthrough=]
f32bit = true;
~~~~~~~^~~~~~
drivers/virt/vboxguest/vboxguest_core.c:1489:2: note: here
case VBG_IOCTL_HGCM_CALL(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.
