From 6c0d57b4e612c00b14852c2f8b179d518462ea6c Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Mon, 31 Aug 2015 17:21:15 +0530 Subject: [PATCH] greybus: connection: protocol can be NULL in gb_connection_exit() gb_connection_exit() is getting called from gb_connection_destroy() now, which will get called from failure path of gb_connection_create_range() (in a later commit). And at that point connection->protocol will be NULL. Don't print an error message if this happens in gb_connection_exit().
