Message-Id: <1381228757-23144-1-git-send-email-csmanjuvijay@gmail.com> Date: Tue, 8 Oct 2013 16:09:17 +0530 From: Majunath Goudar <csmanjuvijay@...il.com> To: linux-arm-kernel@...ts.infradead.org Cc: nataraja.km@....com, Majunath Goudar <csmanjuvijay@...il.com>, David Airlie <airlied@...ux.ie>, Laurent Pinchart <laurent.pinchart+renesas@...asonboard.com>, Sascha Hauer <s.hauer@...gutronix.de>, dri-devel@...ts.freedesktop.org, linux-kernel@...r.kernel.org Subject: [PATCH] SHMOBILE: DRM: Fix backlight_device register and unregister undefined errors. This patch adds a BACKLIGHT_CLASS_DEVICE dependency to configure the DRM_SHMOBILE. Without this patch, build system can lead to build failure. This was observed during randconfig testing, in which DRM_SHMOBILE was enabled w/o BACKLIGHT_CLASS_DEVICE being enabled. Following was the error: Building modules, stage 2. MODPOST 516 modules ERROR: "backlight_device_register" [drivers/gpu/drm/shmobile/shmob-drm.ko] undefined! ERROR: "backlight_device_unregister" [drivers/gpu/drm/shmobile/shmob-drm.ko] undefined! make[1]: *** [__modpost] Error 1 make: *** [modules] Error 2 Signed-off-by: Manjunath Goudar <csmanjuvijay@...il.com> Cc: David Airlie <airlied@...ux.ie> Cc: Laurent Pinchart <laurent.pinchart+renesas@...asonboard.com> Cc: Sascha Hauer <s.hauer@...gutronix.de> Cc: dri-devel@...ts.freedesktop.org Cc: linux-kernel@...r.kernel.org --- drivers/gpu/drm/shmobile/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/shmobile/Kconfig b/drivers/gpu/drm/shmobile/Kconfig index ca498d1..eaf822e 100644 --- a/drivers/gpu/drm/shmobile/Kconfig +++ b/drivers/gpu/drm/shmobile/Kconfig @@ -1,6 +1,6 @@ config DRM_SHMOBILE tristate "DRM Support for SH Mobile" - depends on DRM && (ARM || SUPERH) + depends on DRM && (ARM || SUPERH) && BACKLIGHT_CLASS_DEVICE select DRM_KMS_HELPER select DRM_KMS_CMA_HELPER select DRM_GEM_CMA_HELPER -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
