From 342161c11403ea00e9febc16baab1d883d589d04 Mon Sep 17 00:00:00 2001 From: Li Yang Date: Thu, 20 Apr 2023 22:08:31 +0800 Subject: [PATCH] usb: phy: phy-tahvo: fix memory leak in tahvo_usb_probe() Smatch reports: drivers/usb/phy/phy-tahvo.c: tahvo_usb_probe() warn: missing unwind goto? After geting irq, if ret < 0, it will return without error handling to free memory. Just add error handling to fix this problem.
