The relay code was changed to use irq_work, and it now fails to build if that is disabled:
kernel/relay.o: In function `__relay_reset': relay.c:(.text.__relay_reset+0xb0): undefined reference to `irq_work_sync' kernel/relay.o: In function `relay_close_buf': relay.c:(.text.relay_close_buf+0x14): undefined reference to `irq_work_sync' kernel/relay.o: In function `relay_switch_subbuf': This adds the necessary Kconfig select statement.
