If anyone has any objections, please let me know. ------------------ From: Alex Deucher commit 39d4275058baf53e89203407bf3841ff2c74fa32 upstream. set_power_state defaults to no displays, so we need to update the display configuration after setting up the powerstate on the first call. In most cases this is not an issue since ends up getting called multiple times at any given modeset and the proper order is achieved in the display changed handling at the top of the function.
