Having multiple loadable modules with the same name cannot work
with modprobe, and having both net/qrtr/smd.ko and drivers/soc/qcom/smd.ko
results in a (somewhat cryptic) build error:
ERROR: "qcom_smd_driver_unregister" [net/qrtr/smd.ko] undefined!
ERROR: "qcom_smd_driver_register" [net/qrtr/smd.ko] undefined!

Also, the qrtr driver uses the SMD interface and has a Kconfig dependency,
but also allows for compile-testing when SMD is disabled. However, if
with QCOM_SMD=m and COMPILE_TEST=y we can end up with QRTR_SMD=y and
that fails with a related link error.
The changes the dependency so we can still compile-test the driver but
not have it built-in if SMD is a module, to avoid running in the broken
configuration, and changes the Makefile to provide the driver under
a different module name.

Say Y if you intend to use Qualcomm IPC router protocol. The
|
|
protocol is used to communicate with services provided by other
|
|
hardware blocks in the system.
|
|
|
|
In order to do service lookups, a userspace daemon is required to
|
|
maintain a service listing.

Say Y here to support SMD based ipcrouter channels. SMD is the

most common transport for IPC Router.
