Subject: [Patch V2 2/9] irqdomain: Use consistent prototype for irq_domain_free_irqs_*
Date: Sat, 15 Nov 2014 22:24:00 +0800 [thread overview]
Message-ID: <1416061447-9472-3-git-send-email-jiang.liu@linux.intel.com> (raw)
In-Reply-To: <1416061447-9472-1-git-send-email-jiang.liu@linux.intel.com>
From: Yingjoe Chen <yingjoe.chen@mediatek.com>
When using irq_domain_free_irqs_top() directly in irq_domain_ops, gcc
generate the following warnings:
../drivers/irqchip/irq-gic.c:879:2: warning: initialization from incompatible pointer type [enabled by default]
../drivers/irqchip/irq-gic.c:879:2: warning: (near initialization for 'gic_irq_domain_hierarchy_ops.free') [enabled by default]
Change to use consistent prototype for all irq_domain_free_irqs*
Better to fold this into "irqdomain: Introduce new interfaces to
support hierarchy irqdomains".
