[4.11.0-rc1] kernel warning due to commit 3bb434cd, "vmw_vmci: switch to pci_irq_alloc_vectors"

[íìë]

Â

Hi,

I'm running kernel 4.11-rc1 on VMWare Workstation 12 Pro (Host : windows 10, Guest : Fedora 25).


I got kernel warning with latest kernel.

According to git bisect, first bad commit is [3bb434cdcc6af3d4e70ba041e6f596e465d11e14] vmw_vmci: switch to pci_irq_alloc_vectors.
Reverting the commit removes the warning I see.

Here is the kernel warning ;
