This is a note to let you know that I've just added the patch titled drm: fb_helper: improve CONFIG_FB dependency to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: drm-fb_helper-improve-config_fb-dependency.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 72db727da2eb22cf81e81ba1fdf8a34fa11589a2 Author: Arnd Bergmann <arnd@xxxxxxxx> Date: Fri Oct 29 14:02:38 2021 +0200 drm: fb_helper: improve CONFIG_FB dependency [ Upstream commit 9d6366e743f37d36ef69347924ead7bcc596076e ] My previous patch correctly addressed the possible link failure, but as Jani points out, the dependency is now stricter than it needs to be. Change it again, to allow DRM_FBDEV_EMULATION to be used when DRM_KMS_HELPER and FB are both loadable modules and DRM is linked into the kernel. As a side-effect, the option is now only visible when at least one DRM driver makes use of DRM_KMS_HELPER. This is better, because the option has no effect otherwise.
