Subject: [PATCH v2 08/12] drm/bridge: megachips-stdpxxxx-ge-b850v3-fw: Remove a redundant check on existence of bridge->encoder
Date: Mon, 13 May 2024 23:31:05 +0800

In the ge_b850v3_lvds_create_connector function, the check on the existence
of bridge->encoder is not necessary, as it has already been checked in the
drm_bridge_attach() function called by upstream bridge or driver. Hence, it
is guaranteed that the .encoder member of the drm_bridge instance is not
NULL when cdns_mhdp_connector_init() function get called.

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