From 12867e4e6bf0f55b977261f955a70977f622bf61 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Tue, 29 Mar 2016 10:28:55 +0900 Subject: [PATCH] drm/exynos: Use VIDEO_SAMSUNG_S5P_G2D=n as G2D Kconfig dependency Commit 254d4d111ee1 ("drm/exynos: Add dependency for G2D in Kconfig") made the DRM_EXYNOS_G2D symbol to only be selectable if the s5p-g2d V4L2 driver is not enabled, since both use the same HW IP block. But added the dependency as depends on !VIDEO_SAMSUNG_S5P_G2D which isn't correct since Kconfig expressions are not boolean but tristate. So it will only evaluate to 'n' if VIDEO_SAMSUNG_S5P_G2D=y but it will evaluate to m if VIDEO_SAMSUNG_S5P_G2D=m. This means that both the V4L2 and DRM drivers can be enabled if the former is enabled as a module, which is not what we want.
