diff --git a/drivers/pci/msi.c b/drivers/pci/msi.c index 782b242..242d775 100644 --- a/drivers/pci/msi.c +++ b/drivers/pci/msi.c @@ -41,8 +41,6 @@ int __weak arch_setup_msi_irq(struct pci_dev *dev, struct msi_desc *desc) if (err < 0) return err; - irq_set_chip_data(desc->irq, chip); - return 0; }
Currently, pcie-designware, pcie-rcar, pci-tegra drivers use irq chip_data to 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. Signed-off-by: Yijing Wang <wangyijing@huawei.com> --- drivers/pci/msi.c | 2 -- 1 files changed, 0 insertions(+), 2 deletions(-)
