drm/bridge/synopsys: dsi: Fix dsi_host_transfer() return value

Browse source

The dw_mipi_dsi_host_transfer() must return the number of
bytes transmitted/received on success instead of 0.
Note: As the read feature is not implemented, only the
transmitted number of bytes is returned for the moment.
