From 9ea755f3e8b05445ee6029c6b497a30f1e6a7bf6 Mon Sep 17 00:00:00 2001 From: Aya Mahfouz Date: Wed, 4 Mar 2015 07:35:48 +0200 Subject: [PATCH] staging: xgifb: remove extra parentheses around right bit shift operations Removes extra parentheses around bitwise right shift operations. The cases handled here are when resultant values are assigned to variables. The issue was detected and resolved using the following coccinelle script: @@ expression e, e1; constant c; @@ e = -(e1 +e1 >> -c); +c; @@ identifier i; constant c; type t; expression e; @@ t i = -(e +e >> -c); +c; @@ expression e, e1; identifier f; constant c; @@ e1 = f(..., -(e +e >> -c) +c ,...); Signed-off-by: Aya Mahfouz Signed-off-by: Greg Kroah-Hartman --- drivers/staging/xgifb/XGI_main_26.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/staging/xgifb/XGI_main_26.c b/drivers/staging/xgifb/XGI_main_26.c index 935c714f592a..74e88200726c 100644 --- a/drivers/staging/xgifb/XGI_main_26.c +++ b/drivers/staging/xgifb/XGI_main_26.c @@ -106,7 +106,7 @@ static int XGIfb_mode_rate_to_ddata(struct vb_device_info *XGI_Pr, sr_data = XGI_CRT1Table[index].CR[5]; - HDE = (XGI330_RefIndex[RefreshRateTableIndex].XRes >> 3); + HDE = XGI330_RefIndex[RefreshRateTableIndex].XRes >> 3; cr_data = XGI_CRT1Table[index].CR[3]; @@ -1011,8 +1011,8 @@ static int XGIfb_do_set_var(struct fb_var_screeninfo *var, int isactive, XGIbios_mode[xgifb_info->mode_idx].mode_no); return -EINVAL; } - info->fix.line_length = ((info->var.xres_virtual - * info->var.bits_per_pixel) >> 6); + info->fix.line_length = (info->var.xres_virtual + * info->var.bits_per_pixel) >> 6; xgifb_reg_set(XGISR, IND_SIS_PASSWORD, SIS_PASSWORD);
