From ec518b00f722f9655c1505bbcab25240629cc2af Mon Sep 17 00:00:00 2001 From: Mohammed Shafi Shajakhan Date: Wed, 24 Aug 2011 21:38:07 +0530 Subject: [PATCH] ath9k: Fix PS wrappers in ath9k_set_coverage_class commit 8b2a3827bb12430d932cd479b22d906baf08c212 upstream. this callback is called during suspend/resume and also via iw command. it configures parameters like sifs, slottime, acktimeout in ath9k_hw_init_global_settings where few REG_READ, REG_RMW are also done and hence the need for PS wrappers Signed-off-by: Mohammed Shafi Shajakhan Signed-off-by: John W.
