From 68f95b09c80af7a0b7a27a03227fa802d55f3616 Mon Sep 17 00:00:00 2001 From: Avinash Patil Date: Fri, 23 Aug 2013 16:48:22 -0700 Subject: [PATCH] mwifiex: fix ext_capab IE structure definition EXT_CAPAB_IE format involves IEEE header followed by bytestream of capabilities. Current structure has incorrect member u8 for data; fix it by defining it as u8[0]. Signed-off-by: Avinash Patil Signed-off-by: Bing Zhao Signed-off-by: John W.
