Hi Marc,

I tried that and it doesn't look to work.
I find that for the its_msi_prepare() call, its_dev->shared does not get set, as MSI_ALLOC_FLAGS_SHARED_DEVICE is not set in info->flags.
If I understand the code correctly, MSI_ALLOC_FLAGS_SHARED_DEVICE is supposed to be set in info->flags in platform_msi_set_desc(), but this is called per-msi after its_msi_prepare(), so we don't the flags set at the right time. That's how it looks to me...
Cheers, John
