Date: Mon, 13 Jan 2014 16:26:26 -0800 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Axel Lin <axel.lin@...ics.com>, Simon Horman <horms+renesas@...ge.net.au> Subject: [PATCH 3.10 01/62] irqchip: renesas-irqc: Fix irqc_probe error handling 3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Axel Lin <axel.lin@...ics.com> 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]); Signed-off-by: Axel Lin <axel.lin@...ics.com> Signed-off-by: Simon Horman <horms+renesas@...ge.net.au> Signed-off-by: Greg Kroah-Hartman <gregkh@...uxfoundation.org> --- drivers/irqchip/irq-renesas-irqc.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) --- a/drivers/irqchip/irq-renesas-irqc.c +++ b/drivers/irqchip/irq-renesas-irqc.c @@ -248,8 +248,8 @@ static int irqc_probe(struct platform_de return 0; err3: - for (; k >= 0; k--) - free_irq(p->irq[k - 1].requested_irq, &p->irq[k - 1]); + while (--k >= 0) + free_irq(p->irq[k].requested_irq, &p->irq[k]); irq_domain_remove(p->irq_domain); err2: -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
