From: Paulo Zanoni Date: Mon, 15 Oct 2012 18:51:42 +0000 (-0300) Subject: drm/i915: set the correct function pointers for Haswell DP X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a7902ac548190654c58e2491ff8646701772caa8;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git drm/i915: set the correct function pointers for Haswell DP This is the final remaining piece of Haswell DP enablement. After this patch, just calling intel_dp_init on any port will make DP work. We still do not do this because we're currently initializing HDMI on all the ports, so if we replace intel_hdmi_init with intel_dp_init, we will break HDMI, and we can't call both because they share the same registers.
