[ 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")
