If you, or anyone else, feels it should not be added to the stable tree, please let know about it. >From 134844856c399bfa9462a159dcf860bfdb748055 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Thu, 18 Jun 2026 10:41:57 +0200 Subject: drm/sysfb: Do not page-align visible size of the framebuffer From: Thomas Zimmermann commit 134844856c399bfa9462a159dcf860bfdb748055 upstream. Only return the actually visible size of the system framebuffer in drm_sysfb_get_visible_size_si(). Drivers use this size value for reserving access to framebuffer memory. Increasing the value can make later attempts to do so fail.
