Hi,
This series is based on top of media-tree and some patches where
previously part of the series '[PATCH v5 0/4] v4l2-async: add
subnotifier registration for subdevices'. Hans suggested the cleanups
could be broken out to a separate series, so this is this series :-)
The aim of this series is to cleanup and document some of the odd things
that happens in v4l2_async_notifier_unregister(). The purpose for this
in the short term is to make it easier to implement subnotifiers which
both I and Sakari are trying to address, this feature is blocking other
drivers such as the Renesas R-Car CSI-2 receiver driver. And in the long
run (I hope) to make it easier to get rid of the need to do re-probing
at all in v4l2_async_notifier_unregister() :-)
Niklas Söderlund (4):
v4l: async: fix unbind error in v4l2_async_notifier_unregister()
v4l: async: abort if memory allocation fails when unregistering
notifiers
v4l: async: do not hold list_lock when re-probing devices
v4l: async: add comment about re-probing to
v4l2_async_notifier_unregister()
