+Subject: Revert "tcpm: allow looking for role_sw device in the main node"
+
+From: Xu Yang <xu.yang_2@nxp.com>
+
+commit 6b275bfaa16be3fb1689fa6794e445ecd127a1b4 upstream.
+
+This reverts commit 1366cd228b0c67b60a2c0c26ef37fe9f7cfedb7f.
+
+The fwnode_usb_role_switch_get() returns NULL only if no connection is
+found, returns ERR_PTR(-EPROBE_DEFER) if connection is found but deferred
+probe is needed, or a valid pointer of usb_role_switch.
+
+When switching from a NULL check to IS_ERR_OR_NULL(), usb_role_switch_get()
+returns NULL and overwrites the ERR_PTR(-EPROBE_DEFER) returned by
+fwnode_usb_role_switch_get(). This causes the deferred probe indication to
+be lost, preventing the USB role switch from ever being retrieved.
+
+Fixes: 1366cd228b0c ("tcpm: allow looking for role_sw device in the main node")
