From 60fc5fb66efa0bcbe028637206ed59df8cd4ac19 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Thu, 23 Feb 2012 09:52:28 +0200 Subject: [PATCH] Bluetooth: mgmt: Fix count parameter in get_connections reply This patch fixes the count parameter in the Get Connections reply message. We cannot know the right number until iterating through all connections so set the parameter value only after the loop.
