From c5c779747266cfa103b6acec1e753a383d1c1ebe Mon Sep 17 00:00:00 2001 From: Luis R. Rodriguez Date: Fri, 27 Aug 2010 18:54:36 -0700 Subject: [PATCH 3/3] 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 Cc: stable@kernel.org [2.6.34+] Cc: Amod Bodas Signed-off-by: Luis R.
