From: Chris Wilson Date: Thu, 4 Sep 2014 20:43:45 +0000 (+0100) Subject: drm/i915/hdmi, dp: Do not dereference the encoder in the connector destroy X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=10e972d3f6dd77e009611c4bfeed02fa9827d0d6;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915/hdmi, dp: Do not dereference the encoder in the connector destroy Oops, apparently intel_hdmi/intel_dp is the encoder - an object with a distinct lifetime to the connector, and so we cannot simply reuse the common function to unset and free the edid.
