Unlike DP 1.2 edid corruption test, DP 1.4 requires to calculate

Variable r is being initialized to zero, so the check of a non-zero

It appears that the previous case statements set r to be -EINVAL

Do you have a reference for that move at hand?

The setting of bridge->of_node by drm_bridge_init() in
analogix_dp_core.c is safe, since ->of_node isn't used directly and the
bridge isn't published with drm_bridge_add().

Hi all,
I've dropped the fun parts of this series since they need more work, but
figured drm_bridge_init() as a concept is still valuable on its own (and
I think I'll need it to roll out device links for registered bridges),
so here goes.
v2:
- expanded commit messages and added some extra

No functional change: no logic depends on driver_private being NULL, so
it's safe to set it earlier in exynos_mic_probe.

No functional change: drm_bridge_init() sets bridge->of_node, but that's
not used by msm anywhere, and the bridges aren't published with
drm_bridge_add() for it to matter.
