Subject: drm/i915: don't set up rings on gen6+ for non-kms
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b4178f8aaf84ae59d9b2a17a4a21aa19499f577a;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

drm/i915: don't set up rings on gen6+ for non-kms

It's not supported, and with the patch to refuse loading on gen6+
without kms enabled, there's also no way we can hit this.
