usb: host: ehci-tegra: Fix error handling in tegra_ehci_probe()
If the function platform_get_irq() failed, the negative value returned will not be detected here. So fix error handling in tegra_ehci_probe(). Fixes: 79ad3b5add4a ("usb: host: Add EHCI driver for NVIDIA Tegra SoCs") Acked-by: Alan Stern <stern@rowland.harvard.edu> Acked-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Tang Bin <tangbin@cmss.chinamobile.com> Link: https://lore.kernel.org/r/20201026090657.49988-1-tangbin@cmss.chinamobile.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
