From db1afd18e9cddffd957abea6287a6eae9edbeccc Mon Sep 17 00:00:00 2001 From: Malcolm Priestley Date: Sat, 30 Aug 2014 22:25:46 +0100 Subject: [PATCH] staging: vt6655: replace typedef struct tagSCTS_FB with struct vnt_cts_fb Replacing members b, wDuration_ba, wReserved, wCTSDuration_ba_f0, wCTSDuration_ba_f1, data and reserved2. With b, duration_ba, reserved, cts_duration_ba_f0, cts_duration_ba_f1, 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 | 15 ----------- drivers/staging/vt6655/rxtx.c | 50 +++++++++++++++++++++-------------- drivers/staging/vt6655/rxtx.h | 10 +++++++ 3 files changed, 40 insertions(+), 35 deletions(-) diff --git a/drivers/staging/vt6655/desc.h b/drivers/staging/vt6655/desc.h index 4d9027ef9ef4..5a2bbd2047d8 100644 --- a/drivers/staging/vt6655/desc.h +++ b/drivers/staging/vt6655/desc.h @@ -352,21 +352,6 @@ union vnt_phy_field_swap { u32 field_write;
