Subject: drm: omapdrm: Move DSS_FCK feature to dss driver
Git-commit: 9f0fbaea5cd6b6a0a75a53f99e5c6b3049dd0ce1
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
The FEAT_PARAM_DSS_FCK feature is specific to the DSS, move it from the
omap_dss_features structure to the dss driver.
