It's just complete garbage in commit 7d23e3c37bb3fc6952dc84007ee60cb533fd2d5c Author: Shubhangi Shrivastava <<a href="mailto:shubhangi.shrivastava@intel.com">shubhangi.shrivastava@intel.com</a>> Date: Wed Mar 30 18:05:23 2016 +0530 drm/i915: Cleaning up intel_dp_hpd_pulse Current DP detection has DPCD operations split across intel_dp_hpd_pulse and intel_dp_detect which contains duplicates as well. Also intel_dp_detect is called during modes enumeration as well which will result in multiple dpcd operations. So this patch tries to solve both these by bringing all DPCD operations in one single function and make intel_dp_detect use existing values instead of repeating same steps.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
