genirq: fix devres.o build for GENERIC_HARDIRQS=n (de18836e) · Commits · 戴 / test

kernel/irq/devres.c is built by sparc (32bit) and m68k via the obscure ../../../kernel/irq/devres.o reference in arch/[sparc/m68k]/kernel/Makefile To avoid ifdeffery in devres.c provide request_threaded_irq as an inline for these users. Signed-off-by:
