From a74e7263b53424a7f5b999a11d610231338f5b99 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Wed, 2 Feb 2022 12:33:47 +0100 Subject: greybus: svc: clean up link configuration hack at hello Commit ee2f2074fdb2 ("greybus: svc: reconfig APBridgeA-Switch link to handle required load") added a temporary hack which reconfigures the link at HELLO by abusing the deferred request processing mechanism. Restructure the HELLO request processing so that the link-configuration work is queued before creating the debugfs files and add a comment explaining why it's there.
