+Subject: [PATCH 05/10] fblog: add framebuffer helpers
+
+These helpers scan the system for all available framebuffers and register
+or unregister them. This is needed during startup and stopping fblog so we
+are aware of all connected displays.
+
+The third helper handles mode changes by rescanning the mode and adjusting
+the buffer size.
