   iio:adc:vf610 ensure correct handing of interruption of wait for completion (2014-03-02 21:45:28 +0000)

----------------------------------------------------------------
Third IIO new drivers and cleanups series for 3.15.

New driver
* Xilinx XADC driver -  This has been ready for a while but was awaiting
   a device tree ack (or as it turns out 3+ weeks).

Cleanup
* Drop some unreachable code from mag3110 highlighted by smatch.

Fix
* vf610 - introduced this cycle - put a possible negative error code
   into an unsigned long. Another smatch find - this one promoted by
   guilt that Dan was busy fixing all our messups.

Pulled and pushed out.

What's the status of the remaining drivers/staging/iio/ stuff?  Anything
major keeping them from all moving out of staging sometime soon?

thanks,

I think we are past the point were we can move big chunks of drivers. The 
drivers that are in good shape have already been moved. What's left has 
issues, some smaller, some bigger. Moving things out of staging is 
progressing, but it is progressing one driver at a time.

Fair enough.  How about the "dummy" drivers?  I don't see them listed in
the TODO file, is there a description of what needs to be done for those
that could be done by someone who is new to kernel development to get a
wider range of developers working on this?

thanks,

I started looking at this on the train the other day.  Some drivers are pretty much there
 because their developer moved on and are simple enough that any updates are trivial. 
 I'll start the process of getting these moved sometime soonish.

I think the main issue remaining there is the dubious sysfs interface to create event 'interrupts'. iio_dummy_evgen.c it uses a chained interrupt call so doesn't allow a top
 half and hence doesn't really illustrate a typical driver.

The way it is done in the sysfs trigger is much nicer. However I have been meaning to
 see if there is a general test interrupt source or if not any interest in having one.
