From f5172b0edf2fcc37dfe9b64899c2a318fa462a6b Mon Sep 17 00:00:00 2001 From: Malcolm Priestley Date: Sat, 30 Aug 2014 22:25:45 +0100 Subject: [PATCH] staging: vt6655: replace typedef struct tagSCTS with struct vnt_cts Replacing members b, wDuration_ba, wReserved, data and reserved2 with b, duration_ba, reserved, data and reserved2 unsigned short is replaced with u16 or __le16 where necessary. cast void pointer to pvCTS Creating the new structure in rxtx.h Signed-off-by: Malcolm Priestley Signed-off-by: Greg Kroah-Hartman --- drivers/staging/vt6655/desc.h | 10 ---------- drivers/staging/vt6655/rxtx.c | 46 +++++++++++++++++++++++-------------------- drivers/staging/vt6655/rxtx.h | 9 +++++++++ 3 files changed, 34 insertions(+), 31 deletions(-) diff --git a/drivers/staging/vt6655/desc.h b/drivers/staging/vt6655/desc.h index f0a31a8..4d9027e 100644 --- a/drivers/staging/vt6655/desc.h +++ b/drivers/staging/vt6655/desc.h @@ -355,16 +355,6 @@ union vnt_phy_field_swap { // // CTS buffer header // -typedef struct tagSCTS { - struct vnt_phy_field b;
