Removed unecessary clearing of EoE handlers in master init function;
fixed possible bug on failing to initialize or add master kobject.

Updated TODO.

Respected endianess in sysfs SDO output; Separate message, if data type
does not fit to bit length.

Slave configuration exclusively from master thread; removed
ec_master_sync_io(); introduced events in the master state machine;
locking of slave scanning and slave configuration through allow_scan
and allow_config flags.

Merged changes of examples/mini/mini.c -r858:859 to
examples/rtai/rtai_sample.c.

Minor changes in minimal example.

Fixed missing semaphore initialization.

Added scan time output.

Fixed skipped datagrams when not in FSM idle phase.

Introduced idle flag in master state machine.

Renamed names of enum type ec_request_state_t.

Made waiting for device semaphore uninterruptible.

Replaced master variable 'atomic_t available' by integer and used
semaphore in module.c instead.

Implemented SDO reading with wait queues.

Renamed ec_eeprom_request_state_t enum to ec_request_state_t and made it
global.

Updated TODO.

Removed X:Y addressing scheme, ec_slave_is_coupler(),
ec_master_calc_addressing(), coupler_index and coupler_subindex variables.
Adapted lsec script and examples.

Correctted resetting topology_change_pending and tainted flags.

Adjusted minimal example to interface changes.

Added parameters for vendor ID and product code to ecrt_get_slave(); PDO
registration functions now take a slave pointer as argument; changed
values for ec_bus_status_t.

Allow only MAC addresses as device identifiers; replaced master list by
master array; hand ober MAC addresses with array module parameters.

Updated NEWS and TODO.

Removed ecrt_master_run(), removed datagram queueing from state
