X-Git-Tag: v4.13-rc1~45^2~13^2~100 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=acf1dba661e908e923320b4226bad4d8fc23c6f5;p=platform%2Fkernel%2Flinux-exynos.git drm/i915/cnl: Cannonlake uses CNP PCH. Avoid warning when CNP is detected with CNL. Also let's force it on the virtual detection.
