Dmitry Baryshkov fcbb93f1e4 drm/display: dp: change drm_dp_dpcd_read_link_status() return value ... drm_dp_dpcd_read_link_status() follows the "return error code or number of bytes read" protocol, with the code returning less bytes than requested in case of some errors. However most of the drivers interpreted that as "return error code in case of any error". Switch drm_dp_dpcd_read_link_status() to drm_dp_dpcd_read_data() and make it follow that protocol too.
