From 13803132818cf8084d169617be060fd8e3411a98 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Wed, 9 Sep 2015 16:40:56 +0200 Subject: drm/core: Preserve the framebuffer after removing it. Previously RMFB and fd close chose to disable any plane that had an active framebuffer from this file. If it was a primary plane the crtc was disabled. However the fbdev code or any system compositor should restore the planes anyway so there's no need to do it twice. The old fb_id is zero'd, so there's no danger of being able to restore the fb from fb_id.
