USB: chipidea: msm: fix ulpi-node lookup
Fix child-node lookup during probe, which ended up searching the whole device tree depth-first starting at the parent rather than just matching on its children. Note that the original premature free of the parent node has already been fixed separately, but that fix was apparently never backported to stable. Fixes: 47654a162081 ("usb: chipidea: msm: Restore wrapper settings after reset") Fixes: b74c43156c0c ("usb: chipidea: msm: ci_hdrc_msm_probe() missing of_node_get()") Cc: stable <stable@vger.kernel.org> # 4.10: b74c43156c0c Cc: Stephen Boyd <stephen.boyd@linaro.org> Cc: Frank Rowand <frank.rowand@sony.com> Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Peter Chen <peter.chen@nxp.com>
