This is a separate issue from the originally reported (on two different
machines). The original one was triggered by S3 and probe failed with the
following error:
*ERROR* LSPCON read(0x80, 0x41) failed

The one in patchwork_2888 happens independent of S3 with the following error:
[drm:drm_dp_dual_mode_detect] DP dual mode adaptor ID: 44 (err 0)
[drm:lspcon_init [i915]] No LSPCON detected, found type 1 HDMI
[drm:lspcon_init [i915]] *ERROR* Failed to probe lspcon

In this latter case LSPCON recovers, and looks like the same issue we have with
some type 1 dongles where the read offset during I2C-over-AUX transfers is
ignored by the dongle.
