From de85ec271a864c05e99ad5ffbed9e95d1b65c757 Mon Sep 17 00:00:00 2001 From: Sandor Yu Date: Wed, 5 Jun 2019 16:04:24 +0800 Subject: [PATCH] drm/rockchip: cdn-dp: correct rate in the struct drm_dp_link assignment The value stored in the rate field of struct drm_dp_link should be the actual link-rate and not the bw_code. Right now the driver stores the code and converts it to the rate. So fixup the driver to store the rate itself.
