From 602fae425cf3ade41a4787f8ddf850af418faa3b Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 17 Mar 2016 15:02:52 +0200 Subject: [PATCH] mac80211: don't start dynamic PS timer if not needed If the device implements dynamic PS itself, there's no need to ever start the dynamic powersave timer on RX. While at it, fix up some indentation in this code.
