[XEN PATCH 5/6] vpic/msix: make 'get_slot' static
Posted by Nicola Vetrini 1 year, 3 months ago
The function can become static since it's used only within this file.
This also resolves a violation of MISRA C:2012 Rule 8.4 due to the absence
of a declaration before the function definition.

Nit (typo): In the title you mean "vpci/msix", just like this quoted
commit has it. This is important-ish because we also have "vpic"
elsewhere in the tree. (Can certainly be adjusted while committing.)

Yes, I meant to write 'vpci/msix'.
