From f6099f89e6932a98db82ae72272ef9268b14e6db Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Thu, 7 Mar 2013 16:47:17 +0100 Subject: [PATCH] b43: HT-PHY: move TX fix to the separated function MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On N-PHY after B43_PHY_B_TEST operation there is a call to TX power fix function which iterates over available cores. It matches our HT-PHY code which means it's probably also some TX fix. Signed-off-by: Rafał Miłecki Signed-off-by: John W.
