To fix:

drivers/infiniband/hw/hns/hns_roce_eq.c:477:1: error: unknown type name ‘irqreturn_t’
 static irqreturn_t hns_roce_msi_x_interrupt(int irq, void *eq_ptr)
 ^
drivers/infiniband/hw/hns/hns_roce_eq.c: In function ‘hns_roce_msi_x_interrupt’:
drivers/infiniband/hw/hns/hns_roce_eq.c:485:2: error: implicit declaration of function ‘IRQ_RETVAL’ [-Werror=implicit-function-declaration]
  return IRQ_RETVAL(int_work);

   ret = request_irq(eq_table->eq[j].irq, hns_roce_msi_x_interrupt,
