There's a problem with that patch.

drivers/gpu/drm/i915/intel_dp.c: In function ‘intel_dp_check_mst_status’:
drivers/gpu/drm/i915/intel_dp.c:4265:9: warning: array subscript 10 is above
array bounds of ‘u8[4]’ {aka ‘unsigned char[4]’} [-Warray-bounds]
        !drm_dp_channel_eq_ok(&esi[10], intel_dp->lane_count)) {
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I ran it anyway, and I saw an error:

[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO
underrun
