Subject: [PATCH 0/3] drm/mediatek: Fixes: Stale pointer usage and device leak

A while ago I've found some issues in drm/mediatek and fixed those
but then forgot to send all of the fixes as I was progressing on more.

For whatever reason, I couldn't continue with more fixes and eventually
forgot to send what I had.
Recent series reminded me about those, which we're carrying in the
Collabora MediaTek integration kernel since .. forever, and are tested
on all of the MTK boards that we have in the lab, including MT8173,
MT8183, MT8192, MT8195, MT8188, MT8186 Chromebooks and Genio boards.

The mtk_dp fix was sent months ago, but got ignored - it's included
in this series again anyway.

  drm/mediatek: mtk_disp_ovl: Enable/disable interrupt on bind/unbind
