From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: relay: select CONFIG_IRQ_WORK
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.
