From: Laurent Pinchart Date: Tue, 13 Feb 2018 14:00:46 +0200 Subject: drm: omapdrm: hdmi5: Allocate the omap_hdmi data structure dynamically Git-commit: c44991ce21bef5831b28b36f1da87dceb85bef75 Patch-mainline: v4.17-rc1 References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166 The omap_hdmi private data structure is currently stored as a global variable. While no platform with multiple HDMI5 encoders currently exists nor is planned, this doesn't comply with the kernel device model and should thus be fixed.
