+Subject: [PATCH 1/2] usb: host: xhci-tegra: set MODULE_FIRMWARE for tegra186
+
+Set the MODULE_FIRMWARE for tegra186, it's registered for 124/210 and
+ensures the firmware is available at the appropriate time such as in
+the initrd, else if the firmware is unavailable the driver fails with
+the following errors:
+
+tegra-xusb 3530000.usb: Direct firmware load for nvidia/tegra186/xusb.bin failed with error -2
+tegra-xusb 3530000.usb: failed to request firmware: -2
+tegra-xusb 3530000.usb: failed to load firmware: -2
+tegra-xusb: probe of 3530000.usb failed with error -2
+
+Fixes: 5f9be5f3f899 ("usb: host: xhci-tegra: Add Tegra186 XUSB support")
