Subject: [PATCH v4 1/7] irqdomain: Fix irq_domain_alloc_irqs return check.
Date: Thu, 23 Oct 2014 23:53:09 +0800 [thread overview]
Message-ID: <1414079595-26129-2-git-send-email-yingjoe.chen@mediatek.com> (raw)
In-Reply-To: <1414079595-26129-1-git-send-email-yingjoe.chen@mediatek.com>
Change virq type from unsigned int to int. Otherwise the return value
check for irq_domain_alloc_irqs will always pass.
