You are returning the wrong error code here:

Better do like this:

       rngc->irq = platform_get_irq(pdev, 0);
       if (rngc->irq < 0) {
               dev_err(&pdev->dev, "FSL RNGC couldn't get irq\n");
               clk_disable_unprepare(rngc->clk);
               return rngc->irq;
       }
