This is a note to let you know that I've just added the patch titled video: fbdev: gbefb: Only instantiate device when built for IP32 to the 5.14-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: video-fbdev-gbefb-only-instantiate-device-when-built.patch and it can be found in the queue-5.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit ccc1e73fa963c06a533d222420a3302bcdd82bc5 Author: Mark Brown <broonie@xxxxxxxxxx> Date: Tue Sep 21 22:21:02 2021 +0100 video: fbdev: gbefb: Only instantiate device when built for IP32 [ Upstream commit 11b8e2bb986d23157e82e267fb8cc6b281dfdee9 ] The gbefb driver not only registers a driver but also the device for that driver. This is all well and good when run on the IP32 machines that are supported by the driver but since the driver supports building with COMPILE_TEST we might also be building on other platforms which do not have this hardware and will crash instantiating the driver. Add an IS_ENABLED() check so we compile out the device registration if we don't have the Kconfig option for the machine enabled.
