As reported in commit f8b648bf66 ("net: sunhme: move asm includes to
below linux includes") when including this <asm/*> header before the
needed <linux/*> headers the compilation will fail because of missing
types:
arch/m68k/include/asm/irq.h:66:20: warning: ‘struct pt_regs’ declared inside parameter list will not be visible outside of this definition or declaration
66 | struct pt_regs *));

78 | asmlinkage void do_IRQ(int irq, struct pt_regs *regs);
