Hi Bjorn
Thanks for the comment.
Yes, I will move of_node_put(dsi1) to right after
of_find_mipi_dsi_host_by_node and remove it from err_dsi_device.
Thanks

dsi1 is already put if we came here through err_dsi_device et al.
You don't need to reference dsi1 beyond the call to
of_find_mipi_dsi_host_by_node() to put it before checking the
dsi1_host.
