From: Hans Verkuil <hverkuil-cisco@xxxxxxxxx> Various fixes for bugs that I found while working on the regression test-media script. The CONFIG_DEBUG_KOBJECT_RELEASE=y option in particular found a bunch of bugs where things were not released in the right order. Note that the first two patches are not bug fixes, but they help debugging kobjects. Without this the object name is just (null), which makes it hard to figure out what the object is. Changes since v2: - Extended release callback documentation in patch 6/9 - Added missing documentation for the new owner field in patch 7/9 - Removed trailing . in sd_int_ops documentation in patch 9/9 for consistency. With these changes I can run the test-media script without errors (except for a known vimc 'do not call blocking ops when !TASK_RUNNING;' error, a patch for this from Helen arrived yesterday). Many thanks to Laurent for reviewing this series!
