These should fix the hang in the bug referenced in patch 2/2. Based on some links the actual error might be a firmware bug in the docking station, but we shouldn't trust on DP sinks to not keep replying aux defer indefinitely. Even with the docking station's firmware fixed, this may not be enough to actually get the output working. They are branch devices, possibly MST devices, which we still suck at. But hey, at least we won't freeze the system. The retry timeout and limit are in line with Thierry's dp aux series [1], so this should in fact ease the transition by catching any regressions caused by this change up front. BR, Jani.
