Subject: drm: omapdrm: dss: Don't unnecessarily cast to dev to pdev and back
Git-commit: b40d0ed647a2d96da38760d0429450936030fd85
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

The dss_unbind() function casts the struct device pointer to a struct
platform_device, only to later use the struct device pointer from
platform_device. Don't cast at all.
