From cb551df2028017c71b07db9537efb90abcf9cc7d Mon Sep 17 00:00:00 2001 From: Sujith Date: Tue, 1 Jun 2010 15:14:12 +0530 Subject: [PATCH] ath9k_htc: Add PS wrappers The HW has to be awake when registers are accessed. Ensure this is so by using the PS wrappers at appropriate places. Signed-off-by: Sujith Signed-off-by: John W.
