6.18-stable review patch. If anyone has any objections, please let me know. ------------------ From: Shawn Lin commit 4c0d69d677cf5b0065ebbb3ceb8ba66fddbec630 upstream. rockchip_pm_add_subdomain() ignored the return value of its recursive call, so a failure deeper in the hierarchy was silently dropped and probe still succeeded with an incomplete domain tree.
