Subject[PATCH] dmaengine: dw-edma: Fix build error without CONFIG_PCI_MSI
Date
If CONFIG_PCI_MSI is not set, building with CONFIG_DW_EDMA
fails:

drivers/dma/dw-edma/dw-edma-core.c: In function dw_edma_irq_request:
drivers/dma/dw-edma/dw-edma-core.c:784:21: error: implicit declaration of function pci_irq_vector; did you mean rcu_irq_enter? [-Werror=implicit-function-declaration]
err = request_irq(pci_irq_vector(to_pci_dev(dev), 0),
^~~~~~~~~~~~~~
