    drm/tegra: dsi: Make use of the helper function dev_err_probe()
    
    [ Upstream commit fc75e4fcbd1e4252a0481ebb23cd4516c127a8e2 ]
    
    When possible use dev_err_probe help to properly deal with the
    PROBE_DEFER error, the benefit is that DEFER issue will be logged
    in the devices_deferred debugfs file.
    And using dev_err_probe() can reduce code size, the error value
    gets printed.
