In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
This patch fixes the following warning:
drivers/xen/xen-pciback/xenbus.c: In function ‘xen_pcibk_frontend_changed’:
drivers/xen/xen-pciback/xenbus.c:545:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (xenbus_dev_is_online(xdev))
^
drivers/xen/xen-pciback/xenbus.c:548:2: note: here
case XenbusStateUnknown:
^~~~
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.
