[ 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")
