Description: The Steam deck seems to have issues sleeping with the official
dock. Trigger mem sleep enough times and the deck will give up sleeping.

Hardware: Steam Deck and Official Steam Dock.


Step to reproduce:
1. Plug in the Steam deck into the dock.
2. `echo mem | sudo tee -a /sys/power/state`
3. Wake up the Steam deck with either the power button or the Steam controller
plug into USB. Use the steam button to wake up the deck.
4. Repeat 2-3 until the screen freezes

Expected behavior

The steam deck will sleep properly

Actual behavior

The error will either cause the deck to wake immediately after setting
/sys/power/state to mem or wake up will completely freeze the display.

I cannot reproduce this bug without the official dock. I have not attempt to
reproduce this issue with any other third party docks.
