This is a set of changes which fix some coding style issues in HDP and
some small bugs I've seen reviewing the code.
[PATCH 1/5] hdp_util: Fix coding style issues
[PATCH 2/5] hdp_types: Fix unappropiated field type for dbus watcher
[PATCH 3/5] hdp_util: Fix potential NULL pointer dereference
[PATCH 4/5] hdp_manager: Fix coding style issues
[PATCH 5/5] hdp: Fix coding style issues
