From 008224cdc12628d21a3eb92259fa3aa3ea5b22a1 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 21 Sep 2021 22:21:02 +0100 Subject: [PATCH] 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.
