Subject: [PATCH v1 03/21] MSI: Remove the redundant irq_set_chip_data()
Date: Fri, 5 Sep 2014 18:09:48 +0800 [thread overview]
Message-ID: <1409911806-10519-4-git-send-email-wangyijing@huawei.com> (raw)
In-Reply-To: <1409911806-10519-1-git-send-email-wangyijing@huawei.com>
Currently, pcie-designware, pcie-rcar, pci-tegra drivers
use irq chip_data to save the msi_chip pointer. They
already call irq_set_chip_data() in their own MSI irq map
functions. So irq_set_chip_data() in arch_setup_msi_irq()
is useless.
