[Paul Gortmaker]

To fix:

drivers/infiniband/hw/hns/hns_roce_eq.c:477:1: error: unknown type name âirqreturn_tâ
 static irqreturn_t hns_roce_msi_x_interrupt(int irq, void *eq_ptr)
 ^
drivers/infiniband/hw/hns/hns_roce_eq.c: In function âhns_roce_msi_x_interruptâ:
drivers/infiniband/hw/hns/hns_roce_eq.c:485:2: error: implicit declaration of function âIRQ_RETVALâ [-Werror=implicit-function-declaration]
  return IRQ_RETVAL(int_work);
  ^
drivers/infiniband/hw/hns/hns_roce_eq.c: In function âhns_roce_init_eq_tableâ:
drivers/infiniband/hw/hns/hns_roce_eq.c:711:3: error: implicit declaration of function ârequest_irqâ [-Werror=implicit-function-declaration]
   ret = request_irq(eq_table->eq[j].irq, hns_roce_msi_x_interrupt,
   ^
drivers/infiniband/hw/hns/hns_roce_eq.c:726:3: error: implicit declaration of function âfree_irqâ [-Werror=implicit-function-declaration]
   free_irq(eq_table->eq[j].irq, eq_table->eq + j);
   ^

as seen on arm64 allmodconfig builds.
