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.
