           Summary: kyrofb_check_var misses x-resolution and y-resolution
                    setting?
    Kernel Version: Linux 2.6.20
            Status: NEW
          Severity: normal
             Owner: jsimmons@infradead.org
         Submitter: shanlu@cs.uiuc.edu


Distribution: Linux 2.6.20
Problem Description:

kyrofb_check_var (the function supposed to set up based video mode) seems to
forget set two framebuffer parameters: x-resolution and y-resolution.

The function is in File drivers/video/kyro/fbdev.c
399 static int kyrofb_check_var(struct fb_var_screeninfo *var, struct fb_info *info)
400 {
401  	struct kyrofb_info *par = info->par;
...

In above function, almost every display-related fields (upper-margin,
left-margin, sync, etc.) are set for var based on info->par. But var->x_res and
var->y_res (x-resolution and y-resolution) are not. Why not use par->XRES and
par->YRES to set it?

Also the par->X_RES and par->Y_RES do get set in kyrofb_set_par (in the same
file), together with other field like par->HFP (right margin), HBP
(left_margin). I think check_var should take x,y-resolution from par.
