From 3c62f878a9695111a43dc2c1f90cf4b15efc76a0 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Thu, 7 Jul 2022 16:47:28 +0300 Subject: PCI: dwc: Correct msi_irq condition in dw_pcie_free_msi() The dwc-based drivers set pp->msi_irq to -ENODEV if they do not want the dwc core to do anything with pp->msi_irq. dw_pcie_host_init() sets the handler and data when "pp->msi_irq > 0", so use the same condition when removing the handler and data in dw_pcie_free_msi().
