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
