Switch the order of the loops to walk the rates on the top so we exhaust all DP 1.1 rate/lane combinations before trying DP 1.2 rate/lane combos. This avoids selecting rates that are supported by the monitor, but not the connector leading to valid modes getting rejected. bug: https://bugs.freedesktop.org/show_bug.cgi?id=95206 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> 
commit c47b9e0944e483309d66c807d650ac8b8ceafb57 upstream.

Switch the order of the loops to walk the rates on the top
so we exhaust all DP 1.1 rate/lane combinations before trying
DP 1.2 rate/lane combos.

This avoids selecting rates that are supported by the monitor,
but not the connector leading to valid modes getting rejected.
