You may make it even more effecient (in terms of code readability as I believe
compiler optimizes this anyway to the same):

>  	int i, retval = 0;
>  
>  	for (i = first_fb_vc; i <= last_fb_vc; i++) {
> -		if (con2fb_map[i] == idx)
> +		if (con2fb_map[i] == idx) {
>  			retval = 1;
> +			break;
> +		}

		return 1;

>  	}
>  	return retval;

	return 0;

>  }

...

>  	int i, retval = 0;
>  
>  	for (i = first_fb_vc; i <= last_fb_vc; i++) {
> -		if (con2fb_map[i] != -1)

Ditto.

...

Since it's applied, you can consider a followup.
