From: Marek Szyprowski <m.szyprowski@xxxxxxxxxxx>
Restore the proper bridge chain by finding the previous bridge
in the chain instead of passing NULL.
This establishes a proper bridge chain while attaching downstream
bridges.
v5:
* exclude the NULL replacement in exynos_dsi_host_attach
v4:
* none
v3:
* new patch
