Subject: [PATCH] usb: host: ehci-tegra: Fix error handling in tegra_ehci_probe()
Date: Mon, 26 Oct 2020 17:06:57 +0800 [thread overview]
Message-ID: <20201026090657.49988-1-tangbin@cmss.chinamobile.com> (raw)
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")
