From 5d137dff36dce1eda0617a00eb87b57e48300045 Mon Sep 17 00:00:00 2001 From: Gertjan van Wingerde Date: Mon, 6 Feb 2012 23:45:09 +0100 Subject: [PATCH] rt2x00: Use saved BBP 25 and 26 values when configuring channel on RT3572. This brings the rt2800 channel switching code for RT3572 closer to the v2.5.0.0 Ralink RT3572 driver. Signed-off-by: Gertjan van Wingerde Acked-by: Ivo van Doorn Signed-off-by: John W.
