You shouldn't need this at all. The driver you are looking at is using a deprecated API, and you should implement the MSI part of your driver using the generic MSI layer which takes care of this and shouldn't require exporting this function. There is a number of drivers in the tree that have been converted to generic MSI, such as pcie-tango.c for example. Thanks, M. -- Without deviation from the norm, progress is not possible.
