From 840a6ff50a53064fc7d61cf8e5a0c1aa2e6c3078 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Mon, 8 Mar 2021 09:48:39 +0000 Subject: [PATCH] usb: typec: stusb160x: fix return value check in stusb160x_probe() [ Upstream commit f2d90e07b5df2c7745ae66d2d48cc350d3f1c7d2 ] In case of error, the function device_get_named_child_node() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.
