Subject: [PATCH v5 11/14] irqchip/omap-intc: Fix potential resource leak
Date: Mon, 6 Jul 2020 09:19:22 +0800 [thread overview]
Message-ID: <1593998365-25910-12-git-send-email-yangtiezhu@loongson.cn> (raw)
In-Reply-To: <1593998365-25910-1-git-send-email-yangtiezhu@loongson.cn>
In the function omap_init_irq_of(), system resource "omap_irq_base"
was not released in an error case. Thus add a call of the function
"iounmap" in the if branch.
Fixes: 8598066cddd1 ("arm: omap: irq: move irq.c to drivers/irqchip/")
