[PATCH 0/2] drm/mediatek: fix potential OF node use-after-free

A recent change (included in the drm pull request for 6.17-rc4) fixed a
device reference leak but also introduced a potential OF node
use-after-free.

This series fixes the new OF node reference imbalance and drops the
unnecessary gotos introduced by the broken fix, effectively reverting
that change in favour of the minimal fix I had previously posted here:

	https://lore.kernel.org/lkml/20250722092722.425-1-johan@kernel.org/

These should go into 6.17 which (soon) has the broken fix, which was
also marked for stable backport.
