From cf5d32736722a1abf00c432241a5477c09cd4db2 Mon Sep 17 00:00:00 2001 From: Rehas Sachdeva Date: Tue, 20 Sep 2016 19:40:14 +0530 Subject: [PATCH] staging: xgifb: Remove unused variable and if statement Setting the variable 'refresh_rate = 60;' has no use to the rest of the function. Hence the if statement setting it and the variable itself can be removed. This was detected using the following Coccinelle semantic patch: @@ type T; identifier i; constant C; @@ ( extern T i; | - T i; <+... when != i - i = C; ...+> ) Signed-off-by: Rehas Sachdeva Signed-off-by: Greg Kroah-Hartman --- drivers/staging/xgifb/XGI_main_26.c | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-) diff --git a/drivers/staging/xgifb/XGI_main_26.c b/drivers/staging/xgifb/XGI_main_26.c index a58983f3d402..0c78491ff5a1 100644 --- a/drivers/staging/xgifb/XGI_main_26.c +++ b/drivers/staging/xgifb/XGI_main_26.c @@ -1224,7 +1224,7 @@ static int XGIfb_check_var(struct fb_var_screeninfo *var, struct fb_info *info) unsigned int vtotal = 0; unsigned int drate = 0, hrate = 0; int found_mode = 0; - int refresh_rate, search_idx; + int search_idx; if ((var->vmode & FB_VMODE_MASK) == FB_VMODE_NONINTERLACED) { vtotal = var->upper_margin + var->yres + var->lower_margin @@ -1260,10 +1260,6 @@ static int XGIfb_check_var(struct fb_var_screeninfo *var, struct fb_info *info) xgifb_info->refresh_rate = 60; } - /* Calculation wrong for 1024x600 - force it to 60Hz */ - if ((var->xres == 1024) && (var->yres == 600)) - refresh_rate = 60; - search_idx = 0; while ((XGIbios_mode[search_idx].mode_no != 0) && (XGIbios_mode[search_idx].xres <= var->xres)) {
