From: "yenchia.chen" <yenchia.chen@mediatek.com> We have met a deadlock issue on our device when resuming. After applying this patch which is picked from mainline, issue solved. We'd like to backport to 5.15.y and could you help to review? thanks. [ Upstream commit 3e999770ac1c7c31a70685dd5b88e89473509e9c ] Rafael J.
