From a51c7663f144606a5f08e772fa3e1e4f2277a614 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Mon, 20 Mar 2023 16:07:50 +0100 Subject: drm/fb-helper: Consolidate CONFIG_DRM_FBDEV_LEAK_PHYS_SMEM Consolidate all handling of CONFIG_DRM_FBDEV_LEAK_PHYS_SMEM by making the module parameter optional in drm_fb_helper.c. Without the config option, modules can set smem_start in struct fb_info for internal usage, but not export if to userspace. The address can only be exported by enabling the option and setting the module parameter. Also update the comment.
