From 90921014608d91a03766d0025fa32662dc7c5062 Mon Sep 17 00:00:00 2001 From: Luciano Coelho Date: Sun, 20 Nov 2011 21:40:41 +0200 Subject: wireless/wl12xx/wl1251: move TI WLAN modules to a common ti subdirectory Move wl12xx and wl1251 modules into a new drivers/net/wireless/ti directory. Add a TI WLAN Kconfig option and Makefile to support this change. Signed-off-by: Luciano Coelho Cc: John W.
