[PATCH v4 2/7] PCI: dwc: Correct msi_irq condition in dw_pcie_free_msi()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The subdrivers pass -ESOMETHING if they do not want the core to touch
MSI IRQ. dw_pcie_host_init() also checks if (msi_irq > 0) rather than
just if (msi_irq). So let's make dw_pcie_free_msi() also check that
msi_irq is greater than zero.
