Subject: [PATCH] PCI/MSI: Use msi_mask_irq() in pci_msi_shutdown()
Git-commit: d28d4ad2a1aef27458b3383725bb179beb8d015c
Patch-mainline: v5.14-rc6
References: git-fixes
No point in using the raw write function from shutdown. Preparatory change
to introduce proper serialization for the msi_desc::masked cache.
