Please use obj-$(CONFIG_VMWARE_VMCI) += vmw_vmci/
like we do in the other cases. This prevents us from visiting the directory
when this feature is not enabled.

please use:
vmw_vmci-y += vmci_context.o
vmw_vmci-y += vmci_datagram.o
vmw_vmci-y += vmci_doorbell.o
This is recommended these days and allows you to enable/disable
single files later using a config option.

Use inverse chrismas tree here.
Longer include lines first, and soret alphabetically when
lines are of the same length.
This applies likely in many cases.

Looks like poor obscufation.
Use a statis inline function if you need a helper for this.

The kernel types are u32 not uint32_t - these types belongs in user-space.

The kernel style is to use lower_case for everything.
So this would become:
vmci_device_get()
This is obviously a very general comment and applies everywhere.
