[PATCH] usb: host: ehci-tegra: Fix error handling in tegra_ehci_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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")
