workqueue: avoid using deprecated functions

2012-10-02T23:01:31+00:00

The network merge brought in a few users of functions that got
deprecated by the workqueue cleanups: the 'system_nrt_wq' is now the
same as the regular system_wq, since all workqueues are now non-
reentrant.

Similarly, remove one use of flush_work_sync() - the regular
flush_work() has become synchronous, and the "_sync()" version is thus
deprecated as being superfluous.

NFC: Use system_nrt_wq instead of custom ones

2012-09-24T22:17:23+00:00

NFC is using a number of custom ordered workqueues w/ WQ_MEM_RECLAIM.
WQ_MEM_RECLAIM is unnecessary unless NFC is gonna be used as transport
for storage device, and all use cases match one work item to one
ordered workqueue - IOW, there's no actual ordering going on at all
and using system_nrt_wq gives the same behavior.

There's nothing to be gained by using custom workqueues.  Use
system_nrt_wq instead and drop all the custom ones.

NFC: nfc_driver_failure() implementation

2012-07-09T20:42:11+00:00

If the device is polling we sent a 0 target found event.

NFC: nfc_targets_found() should accept zero target found

2012-07-09T20:42:10+00:00

The semantics for a zero target found event is that the polling operation
could not complete.

NFC: Core must test the device polling state inside the device lock

2012-07-09T20:42:09+00:00

There can ever be only one call to nfc_targets_found() after polling
has been engaged. This could be from a target discovered event from
the driver, or from an error handler to notify poll will never complete.

NFC: Driver failure API

2012-07-09T20:42:08+00:00

This API should be used by drivers, HCI, SHDLC or NCI stacks to report an
unrecoverable error.

NFC: Call the DEP link down ops even when in target mode

2012-06-04T19:34:31+00:00

Even in target mode we need to let the driver know that we want to
bring the DEP link down.

NFC: Introduce target mode rx data callback

2012-06-04T19:34:31+00:00

This routine will be called by drivers whenever they receive data in target
mode. This should be unexpected events and as such should be handled by a
standalone API (i.e. not as a callback pointer from an existing API).
