The dsi_get_dsidrv_data() and dsi_get_dsidev_from_dssdev() inline functions convert a struct omap_dss_device pointer to the corresponding struct platform_device, and a struct platform_device pointer to the corresponding struct dsi_data. They are nearly always called together without any use of the intermediate platform_device, so combine them into a single function.
In the three locations where only dsi_get_dsidrv_data() is used, call dev_get_drvdata() directly.
