driver core: faux: Quiet probe failures
The acpi-einj conversion to faux_device_create() leads to a noisy error message when the error injection facility is disabled. Quiet the error as CXL error injection via ACPI expects the module to stay loaded even if the error injection facility is disabled. This situation arose because CXL knows proper kernel named objects to trigger errors against, but acpi-einj knows how to perform the error injection. The injection mechanism is shared with non-CXL use cases. The result is CXL now has a module dependency on einj-core.ko, and init/probe failures are handled at runtime.
