From 7fa530ad1b2d160ec9e76b3b5a1ac2e302e8f3bf Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Wed, 25 Nov 2015 15:59:23 +0100 Subject: [PATCH] greybus: control: do not assume a control bundle The control bundle is going away so update the code. Also remove defensive WARN_ON which would not just warn if our implementation is broken, but also leak further memory unnecessarily.
