From d1b163aa0749706379055e40a52cf7a851abf9dc Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Tue, 23 Jan 2024 13:09:26 +0100 Subject: [PATCH] Revert "drivers/firmware: Move sysfb_init() from device_initcall to subsys_initcall_sync" This reverts commit 60aebc9559492cea6a9625f514a8041717e3a2e4. Commit 60aebc9559492cea ("drivers/firmware: Move sysfb_init() from device_initcall to subsys_initcall_sync") messes up initialization order of the graphics drivers and leads to blank displays on some systems. So revert the commit. To make the display drivers fully independent from initialization order requires to track framebuffer memory by device and independently from the loaded drivers. The kernel currently lacks the infrastructure to do so.
