[PATCH v2 03/12] drm/bridge: nxp-ptn3460: Remove a redundant check on existence of bridge->encoder

[Sui Jingfeng]

Because the existence of 'bridge->encoder' has already been checked before
the ptn3460_bridge_attach() function get called, and drm_bridge_attach()
will quit with a negative error code returned if it fails for some reasons.
Hence, it is guaranteed that the .encoder member of the drm_bridge instance
is not NULL when the ptn3460_bridge_attach() function get called.

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