I didn't apply the other two patches in your branch, since they looked irrelevant. Result is no screen.. In the new dmesg I added, it looks like the quirk is detected too late in the process, so it is as if no quirk is present when it is needed, and the wrong panel type is picked. At least the quirk itself works well! :)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
