Reordering of the device nodes based on unit address resulted in ge_b850v3_lvds_attach() being called before ge_b850v3_lvds_ptr->stdp4028_i2c was populated. This patch moves the drm bridge initialization from ge_b850v3_lvds_init() to stdp4028_ge_b850v3_fw_probe() ensuring that ge_b850v3_lvds_ptr->stdp4028_i2c is properly populated.
