From: Arnd Bergmann Date: Thu, 29 Jan 2015 16:16:38 +0000 (+0100) Subject: drm: shmobile: fix Kconfig dependencies X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=56a8620a15bbc05d8ef57ace7fc769372de1178a;p=openwrt%2Fstaging%2Fblogic.git drm: shmobile: fix Kconfig dependencies The shmobile drm driver selects BACKLIGHT_CLASS_DEVICE as of 0a5a5499ad88 "drm: shmobile: Add dependency on BACKLIGHT_CLASS_DEVICE", but that option in turn depends on BACKLIGHT_LCD_SUPPORT, so we actually have to select both, or alternatively use 'depends on BACKLIGHT_CLASS_DEVICE'. Further, the driver uses FB_SH_MOBILE_MERAM if that is enabled, but this breaks if MERAM is a module while the DRM driver is built-in. To solve this, add a dependency on "FB_SH_MOBILE_MERAM || !FB_SH_MOBILE_MERAM", which forces DRM_SHMOBILE to be a module if FB_SH_MOBILE_MERAM set to 'm'.
