Subject: irqchip: renesas-irqc: Fix irqc_probe error handling
From: Axel Lin <axel.lin@xxxxxxxxxx>
commit dfaf820a13ec160f06556e08dab423818ba87f14 upstream.
The code in goto err3 path is wrong because it will call fee_irq() with k == 0,
which means it does free_irq(p->irq[-1].requested_irq, &p->irq[-1]);
