Subject: [PATCH 3/3] greybus: svc: clean up link configuration hack at hello
Date: Wed,  2 Feb 2022 12:33:47 +0100	[thread overview]
Message-ID: <20220202113347.1288-4-johan@kernel.org> (raw)
In-Reply-To: <20220202113347.1288-1-johan@kernel.org>

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.
