6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Harry Wentland <harry.wentland@xxxxxxx> commit 78aca9ee5e012e130dbfbd7191bc2302b0cf3b37 upstream. This causes flicker on a bunch of eDP panels. The info_packet code also caused regressions on other OSes that we haven't' seen on Linux yet, but that is likely due to the fact that we haven't had a chance to test those environments on Linux. We'll need to revisit this. This reverts commit 202260f64519e591b5cd99626e441b6559f571a3.
