Subject: [PATCH] drm/bridge: megachips-stdpxxxx-ge-b850v3-fw: Remove a redundant check on existence of bridge->encoder
In the ge_b850v3_lvds_create_connector function, the check on the existence
of bridge->encoder is not necessary, as it has already been done 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
ge_b850v3_lvds_attach() function gets called.
Remove the redundant checking codes "if (!bridge->encoder) { ... }".
