Hi,
The warning is fixed by this patch:
https://www.spinics.net/lists/kvm/msg227575.html
The errors are caused by the fact that the vfio fsl-mc patches have a
dependency on the fsl-mc bus series. For this particular error the
missing patch is: bus/fsl-mc: Export IRQ pool handling functions

Currently the success path in function vfio_fsl_mc_reflck_attach is
returning an uninitialized value in variable ret. Fix this by setting
this to zero to indicate success.
