[PATCH 5.12 175/677] usb: typec: stusb160x: fix return value check in stusb160x_probe()

From: Greg Kroah-Hartman

From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

[ 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.

Fixes: da0cb6310094 ("usb: typec: add support for STUSB160x Type-C controller family")
