The driver overrides the error codes (and also IRQ0) returned by platform_get_irq() to -ENODEV, so if it returns -EPROBE_DEFER, the driver will fail the probe permanently instead of the deferred probing. Switch to propagating the error codes upstream -- that means we have to explicitly filter out IRQ0 as bad since usb_add_hcd() doesn't quite like it... :-) Fixes: e96ffe2f9deb ("USB: add Marvell Orion USB host support") Signed-off-by: Sergey Shtylyov <s.shtylyov@xxxxxx> --- drivers/usb/host/ehci-orion.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/drivers/usb/host/ehci-orion.c b/drivers/usb/host/ehci-orion.c index 3626758b3e2a..4fa77883f901 100644 --- a/drivers/usb/host/ehci-orion.c +++ b/drivers/usb/host/ehci-orion.c @@ -222,8 +222,12 @@ static int ehci_orion_drv_probe(struct platform_device *pdev) pr_debug("Initializing Orion-SoC USB Host Controller\n"); irq = platform_get_irq(pdev, 0); - if (irq <= 0) { - err = -ENODEV; + if (irq < 0) { + err = irq; + goto err; + } + if (!irq) { + err = -EINVAL; goto err; } -- 2.26.3
