There are a few compile warnings if I moved asm/irq.h to the top of
all included files.
Warning details are below:

In file included from drivers/tty/serial/sprd_serial.c:14:0:
./arch/arm64/include/asm/irq.h:6:39: warning: ?struct pt_regs?
declared inside parameter list [enabled by default]
extern void (*handle_arch_irq)(struct pt_regs *);
^
./arch/arm64/include/asm/irq.h:6:39: warning: its scope is only this
definition or declaration, which is probably not what you want
[enabled by default]
./arch/arm64/include/asm/irq.h:8:54: warning: ?struct pt_regs?
declared inside parameter list [enabled by default]
extern void set_handle_irq(void (*handle_irq)(struct pt_regs *));

Thanks,
