From 6420014ca4a6b0e853c9a19a8649d93682a5bdac Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Sun, 13 Sep 2009 22:05:04 -0700 Subject: ath9k: remove ath9k 25 MHz HT40 spacing stuff This was for supporting 25 MHz spacing for HT40, this is not used as we use 20 MHz spacing instead for HT40 as per 802.11n. The hardware is capable of it though so we leave the phymode definition and EEPROM parsing for it. If some experimenter wants to work on this stuff stuff you can add an extension enabling bool on ath_common and perhaps some debugfs knob to enable it. Keep in mind you'll also need to update the phymode with the AR_PHY_FC_DYN2040_EXT_CH which has been left on the driver. Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.

Simplify this by having the hw initialization call the rf bank allocation directly for external radios. Also, propagate an -ENOMEM properly now upon failure. Signed-off-by: Luis R.
