Subject[PATCH 5.16 157/186] drm/bridge: ti-sn65dsi86: Properly undo autosuspend
Date
From: Douglas Anderson <dianders@chromium.org>

[ Upstream commit 26d3474348293dc752c55fe6d41282199f73714c ]

The PM Runtime docs say:
Drivers in ->remove() callback should undo the runtime PM changes done
in ->probe(). Usually this means calling pm_runtime_disable(),
pm_runtime_dont_use_autosuspend() etc.

We weren't doing that for autosuspend. Let's do it.

Fixes: 9bede63127c6 ("drm/bridge: ti-sn65dsi86: Use pm_runtime autosuspend")
