genirq: Mark expected switch case fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
With -Wimplicit-fallthrough added to CFLAGS:
kernel/irq/manage.c: In function ‘irq_do_set_affinity’:
kernel/irq/manage.c:198:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
cpumask_copy(desc->irq_common_data.affinity, mask);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
kernel/irq/manage.c:199:2: note: here
case IRQ_SET_MASK_OK_NOCOPY:
^~~~
Annotate it.
