From edbf51f65eefb952a03c00eadefa9aa48580fcc6 Mon Sep 17 00:00:00 2001 From: Sujith Date: Thu, 17 Sep 2009 09:28:41 +0530 Subject: [PATCH] ath9k: Fix regression in PA calibration The commit "ath9k: Fix bugs in programming registers during PA CAL" removed a REG_READ of 0x7834. This resulted in incorrect computation of the subsequent value to be written in RF2G6. This patch fixes the regression by re-adding the REG_READ. Signed-off-by: Sujith Signed-off-by: John W.
