The bridge_node is unnecessary between FIMD and DSIM. If don't remove error handling, it will not work between FIMD and DSIM. So remove error handling.

Please make sure to describe why bridge_node is unnecessary. For example, In case of Exynos SoC, a bridge device such as mDNIe and MIC could be placed between Display Controller and MIPI DSI device but the bridge device is required optionally.

Thanks, Inki Dae

Remove the error handling for bridge_node because the bridge_node is required optionally. It has already been described in commit message.

For example, In case of Exynos 3250 SoC, no bridge_node is required between FIMD and MIPI DSI.
