Subject: [PATCH v2 10/12] drm/bridge: lt9611uxc: Remove a redundant check on existence of bridge->encoder

In the lt9611uxc_connector_init() function, the check on the existence
of bridge->encoder is not necessary, as it has already been checked in
the drm_bridge_attach() function. And the check on the drm bridge core
happens before check in the implementation. Hence, it is guaranteed that
the .encoder member of the struct drm_bridge is not NULL when
lt9611uxc_connector_init() function get called.

Remove the redundant checking codes "if (!bridge->encoder) { ... }".
