request_irq() after setting IRQ_NOAUTOEN as below irq_set_status_flags(irq, IRQ_NOAUTOEN); request_irq(dev, irq...); can be replaced by request_irq() with IRQF_NO_AUTOEN flag. this patch is made base on "add IRQF_NO_AUTOEN for request_irq" which is being merged: https://lore.kernel.org/patchwork/patch/1388765/ Signed-off-by: Tian Tao <tiantao6@hisilicon.com> --- drivers/perf/arm_pmu.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-)
