Is this supposed to fix https://bugs.freedesktop.org/show_bug.cgi?id=98742 ? If so, the Fixes: line seems wrong because f79f26921ee1 isn't in 4.9 where I see the issue. If I want to fix 4.9---my ultimate goal is to fix the kernel that will go into the next stable release---I have to cherry-pick f79f26921ee1 first, I assume? Best regards Uwe
