From 66d6dd45eee2893f249a13406e112a35cc86c987 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 24 May 2017 17:49:58 +0200 Subject: [PATCH] drm/pl111: fix warnings without CONFIG_ARM_AMBA The driver is written in a way to enable compile-testing without CONFIG_ARM_AMBA, but it just causes needless warnings: drivers/gpu/drm/pl111/pl111_drv.c:149:26: error: 'pl111_drm_driver' defined but not used [-Werror=unused-variable] drivers/gpu/drm/pl111/pl111_drv.c:81:12: error: 'pl111_modeset_init' defined but not used [-Werror=unused-function] This unhides the probe/remove functions again and just leaves the driver object as unused when CONFIG_ARM_AMBA is disabled, with a __maybe_unused annotation to shut up the warning.
