Summary
An optional feature of PCI MSI called "Multiple Message" allows a
device to use multiple consecutive interrupt vectors. Unlike for MSI-X,
the setting up of these consecutive vectors needs to happen all in one
go. In this handling an error path could be taken in different
situations, with or without a particular lock held. This error path
wrongly releases the lock even when it is not currently held.
