  Thinkpad X1 yoga:
  CPU: Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz (family: 0x6, model: 0x8e, 
stepping: 0xa)
  GPU: Intel Corporation Device [8086:5917] (rev 07) (prog-if 00 [VGA 
controller])

  Steps:
  1, Connect an external monitor
  2, Try to switch display modes in mirrored, extended, displayed on external 
or internal.

  [Impact]
  External HDMI monitor failed to show screen on Lenovo X1 yoga/carbon

  [Fix]
  Add a workaround to bypass this TMDS_OE writing on identified laptop models.

  [Test Case]
  Tested on ThinkPad X1 yoga 2nd/3rd and Carbon 6th, external HDMI output
  OK.

  [Regression Potential]
  Low, it limits to ThinkPad specific laptops.

A request had been sent to Intel to make a better solution to solve this
issue. This patch is a WA before Intel fix it.
So this patch will not be going upstream.

Upstream bug: https://bugs.freedesktop.org/show_bug.cgi?id=100226
