ps_featuredproducts show only in stock products

[Varguolis]

Hello,

Can somebody tell me how to hide out of stock products in ps_featuredproducts module?

Tried to use 

if($rawProduct['quantity'] < 1) continue;

But this way it just skips and instead of showing 20 items it shows 20 - skips. Is there better way around it?

Thank you in advance
