drm/bridge: select_bus_fmt_recursive(): put the bridge obtained by drm_bridge_get_prev_bridge()

Browse source

The bridge returned by drm_bridge_get_prev_bridge() is refcounted. Put it
when done.

select_bus_fmt_recursive() has several return points, and ensuring
drm_bridge_put() is always called in the right place would be error-prone
(especially with future changes to the select_bus_fmt_recursive() code) and
make code uglier. Instead use a scope-based free, which is future-proof and
a lot cleaner.
