Rodriguez" Date: Thu, 16 Sep 2010 15:12:36 -0400 Subject: [PATCH] ath9k: fix regression which disabled ps on ath9k The patch titled "ath9k: Add new file init.c" shuffled some code around but in dong so for some reason also removed the revision check for disablign power save. Add this revision check again so we can get power save re-enabled again by default on cards newer than AR5416 and AR5418. $ git describe --contains 556242049cc3992d0ee625e9f15c4b00ea4baac8 v2.6.34-rc1~233^2~49^2~343 This patch has fixes for stable kernels [2.6.34+].
