[ Upstream commit 604c75893a01c8a3b5bd6dac55535963cd44c3f5 ]
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: 18a6c866bb19 ("usb: typec: tps6598x: Add USB role switching logic")
