From: Paulo Zanoni Date: Fri, 26 Oct 2012 21:05:48 +0000 (-0200) Subject: drm/i915: split intel_dp_init into encoder and connector pieces X-Git-Tag: v5.15~21041^2~192^2~83 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=f0fec3f2b6b66de5d0ab539a3ed529a3575db98c;p=mirror_ubuntu-kernels.git drm/i915: split intel_dp_init into encoder and connector pieces Same reason as the previous HDMI commit: the DDI code will have its own encoder init function but still use the DP and HDMI connectors.
