From 5a2f0a0bdf201e2183904b6217f9c74774c961a8 Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Mon, 7 Sep 2020 12:00:04 +0100 Subject: [PATCH] firmware: arm_scmi: Move scmi bus init and exit calls into the driver In preparation to enable building scmi as a single module, let us move the scmi bus {de-,}initialisation call into the driver. The main reason for this is to keep it simple instead of maintaining it as separate modules and dealing with all possible initcall races and deferred probe handling. We can move it as separate modules if needed in future.
