Subject: [PATCH 5.13 169/223] usb: gadget: Fix Unbalanced pm_runtime_enable in tegra_xudc_probe

From: Zhang Qilong <zhangqilong3@...wei.com>

commit 5b01248156bd75303e66985c351dee648c149979 upstream.

Add missing pm_runtime_disable() when probe error out. It could
avoid pm_runtime implementation complains when removing and probing
again the driver.

Fixes: 49db427232fe ("usb: gadget: Add UDC driver for tegra XUSB device mode controller")
