[PATCH v2 05/21] drm/exynos: Don't reset bridge->next

[Boris Brezillon]

bridge->next is only points to the new bridge if drm_bridge_attach()
succeeds. No need to reset it manually here.

Note that this change is part of the attempt to make the bridge chain
a double-linked list. In order to do that we must patch all drivers
manipulating the bridge->next field.

Changes in v2:
* Add Laurent's R-b (I'd like to have a R-b from the DRM exynos
  maintainers before applying that one)
