From 9f0871090d031ad656d1d1e77f2881c9a864b343 Mon Sep 17 00:00:00 2001 From: nbd Date: Tue, 27 Mar 2012 13:21:53 +0000 Subject: ath9k: make endian check optional Turns out it triggers on some AR71xx devices where no swapping should be done. Enable endian check for the lantiq target. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@31084 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- .../patches/501-ath9k-eeprom_endianess.patch | 58 +++++++++++++++++++++- 1 file changed, 56 insertions(+), 2 deletions(-) (limited to 'package/mac80211/patches') diff --git a/package/mac80211/patches/501-ath9k-eeprom_endianess.patch b/package/mac80211/patches/501-ath9k-eeprom_endianess.patch index 25d5450a79..3d74cac022 100644 --- a/package/mac80211/patches/501-ath9k-eeprom_endianess.patch +++ b/package/mac80211/patches/501-ath9k-eeprom_endianess.patch @@ -9,7 +9,7 @@ u32 sum = 0, el; bool need_swap = false; int i, addr, size; -@@ -277,27 +277,15 @@ static int ath9k_hw_def_check_eeprom(str +@@ -277,27 +277,16 @@ static int ath9k_hw_def_check_eeprom(str return false; } @@ -34,7 +34,8 @@ - "Invalid EEPROM Magic.
