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. Signed-off-by: Gustavo A. R.
