From 9c8ee3c7341393811d5be5eb61b815e76f92c799 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 8 Sep 2014 17:17:13 +0200 Subject: [PATCH] video: mx3fb: always enable BACKLIGHT_LCD_SUPPORT Commit 7edaa761ee81b ("video: mx3fb: Add backlight control support") changed the mx3fb driver so it always selects the BACKLIGHT_CLASS_DEVICE symbol, but that is hidden behind BACKLIGHT_LCD_SUPPORT in Kconfig, so we get a Kconfig warning for multi_v5_defconfig, which doesn't have that: Warning: (DRM_RADEON && DRM_NOUVEAU && DRM_I915 && DRM_GMA500 && DRM_SHMOBILE && DRM_TILCDC && FB_BACKLIGHT && FB_MX3 && USB_APPLEDISPLAY && FB_OLPC_DCON && ASUS_LAPTOP && SONY_LAPTOP && THINKPAD_ACPI && EEEPC_LAPTOP && ACPI_CMPC && SAMSUNG_Q10) selects BACKLIGHT_CLASS_DEVICE which has unmet direct dependencies (HAS_IOMEM && BACKLIGHT_LCD_SUPPORT) This makes sure we always enable both symbols together for mx3fb, like we do for the other drivers that can't be built without backlight support. Note that a better solution would be to ensure the driver can work with or without backlight support.
