If anyone has any objections, please let me know. ------------------ From: Askar Safin [ Upstream commit 2d967310c49ed93ac11cef408a55ddf15c3dd52e ] Dell Precision 7780 often wakes up on its own from suspend. Sometimes wake up happens immediately (i. e. within 7 seconds), sometimes it happens after, say, 30 minutes.
