From 3281cc7e341b6dc029965c74a8dd3be5e942a63c Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Mon, 30 Jun 2014 15:37:51 -0700 Subject: [PATCH] drm/plane-helper: Use proper plane init function drm_plane_init() (the legacy plane initialization function) takes a bool as its final parameter; originally this indicated whether a plane was 'private' to the driver (before the DRM core understood non-overlay planes), now it indicates whether the plane is a primary plane (private planes were used by some drivers to represent primary planes internally). The newer drm_universal_plane_init() take an 'enum drm_plane_type' as its final parameter to allow the caller to specify the specific plane type desired (primary, cursor, or overlay). Due to a rebasing mistake, the primary plane helper is currently passing DRM_PLANE_TYPE_PRIMARY (enum value = 1) for drm_plane_init()'s boolean 'is_primary' parameter. This winds up giving the correct behavior since DRM_PLANE_TYPE_PRIMARY evaluates as true, but is confusing to anyone reading the code since we're passing an enum value (one of three possible values) for a boolean parameter. Replace the primary plane helper's call to drm_plane_init() with drm_universal_plane_init() so that the parameter and value types match up as expected.
