[PATCH 2/2] firmware: arm_scmi: Add module aliases to i.MX vendor protocols

[Cristian Marussi]

Using the pattern 'scmi-protocol-0x<PROTO_ID>-<VEND_ID>' as MODULE_ALIAS
allows the SCMI core to autoload this protocol, if built as a module, when
its protocol operations are requested by an SCMI driver.
