Suggested-by: Rafael J. Wysocki Signed-off-by: Jonathan Cameron Acked-by: Rafael J. Wysocki Reviewed-by: Gavin Shan --- v5: New patch. Note that for now no arch_register_cpu() calls return -EPROBE_DEFER so it has no impact until the arm64 one is added later in this series. --- drivers/base/cpu.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/base/cpu.c b/drivers/base/cpu.c index 56fba44ba391..b9d0d14e5960 100644 --- a/drivers/base/cpu.c +++ b/drivers/base/cpu.c @@ -558,7 +558,7 @@ static void __init cpu_dev_register_generic(void) for_each_present_cpu(i) { ret = arch_register_cpu(i); - if (ret) + if (ret != -EPROBE_DEFER) pr_warn("register_cpu %d failed (%d)\n", i, ret); } }
