Subject: drm/exynos: Don't reset bridge->next
Git-commit: bd19c4527056b3e42e8c286136660aa14d0b6c90
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

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.
