I checked out the commit before f7655d42fcee and was able to build the kernel. Then I checked out f7655d42fcee and the build failed in the same manner as at 5.6-rc1. Simply reverting f7655d42fcee at 5.6-rc1 does not result in a buildable kernel due to other related changes. -Frank > > > The build error also goes away if I comment out the two lines added to cea_mode_for_vic(): > > if (vic >= 193 && vic < 193 + ARRAY_SIZE(edid_cea_modes_193)) > return &edid_cea_modes_193[vic - 193]; > > > -Frank > _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
