[PATCH 08/15] Rename red_channel_pipe_item_init to red_pipe_item_init

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Christophe Fergeau <cfergeau@xxxxxxxxxx>

The RedChannel argument is not used by red_pipe_item_init. Removing it
will make code simpler in places where we don't have a RedChannel
directly available.
