From 70bb9193728627e84e02eb0960b0aa138ae2cef5 Mon Sep 17 00:00:00 2001 From: Simon Ser Date: Mon, 26 Oct 2020 14:12:30 +0100 Subject: drm: deprecate DRM_FORMAT_MOD_NONE DRM_FORMAT_MOD_NONE is in the list of vendors, which is pretty confusing. We already have DRM_FORMAT_MOD_VENDOR_NONE. Move it down in the list of format modifiers. DRM_FORMAT_MOD_NONE is an alias for DRM_FORMAT_MOD_LINEAR, however the name is confusing: NONE doesn't mean that the modifier is implicit, instead it means that the layout is linear. Deprecate it.
