* tree-wide: use reinit_completion instead of INIT_COMPLETIONWolfram Sang2013-11-151-1/+1
| | | | | | | | | | | | Use this new function to make code more comprehensible, since we are reinitialzing the completion, not initializing.

* tty: metag_da: avoid getting tty kref in dashtty_timer()James Hogan2013-02-061-17/+14Star
| | | | | | | | | | | Getting the tty kref in dashtty_timer() is no longer necessary since it isn't needed in fetch_data() any longer (due to changes which make the tty flip functions refer to tty_ports instead of tty_structs), so just pass around a channel number instead.
