Hi,
v5.4.y commit 31b169a8bed7 ("drm/msm/dsi: Use pm_runtime_resume_and_get to prevent refcnt leaks"), which is commit 3d07a411b4fa upstream, broke display on Dragonboard 845c(sdm845). Cherry-picking commit 6ab502bc1cf3 ("drm/msm/dsi: Enable runtime PM") from the original patch series https://patchwork.freedesktop.org/series/119583/ and it's dependent runtime PM helper routines as suggested by Dmitry https://lore.kernel.org/stable/CAA8EJpo7q9qZbgXHWe7SuQFh0EWW0ZxGL5xYX4nckoFG... fixes that display regression on DB845c.
We need fixes for all of the newer stable trees too, you can't fix an issue in an old tree and then if you upgraded, you would run into that issue again.
So please, resend this series as a set of series for all active lts kernels, and we will be glad to queue them up.
Ack. I'll send the patch series for all the active LTS kernels tomorrow after build/boot testing them locally. Meanwhile please consider this patch series for v5.4.y anyway.
