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