This case specifically happens when spi_w8r8() fails with a

As the error is rather unlikely to happen after the device

iio:trigger: Experimental kthread tight loop trigger (thread only)
This patch is in response to that of
Gregor Boirie <gregor.boirie@parrot.com>
who proposed using a tight kthread within a device driver (be it with the
support factored out into a helper library) in order to basically spin as
fast as possible.
It is meant as a talking point rather than a formal proposal of the code
(though we are heading towards that I think).
Also gives people some working code to mess around with.
I proposed that this could be done with a trigger with a few constraints
and this is the proof (be it ugly) of that.
There are some constraints though, some of which we would want to relax
if this were to move forward.
* Will only run the thread part of the registered pollfunc. This is to
avoid the overhead of jumping in and out of interrupt context. Is the
overhead significant? Not certain but feels like it should be!
* This limitation precludes any device that 'must' do some work in
interrupt context. However, that is true of few if any drivers and
I suspect that any that do will be restricted to using triggers they
provide themselves. Usually we have a top half mainly to grab a
timestamp as soon after the dataready type signal as possible.

The I2C drivers have an i2c_device_id array but that information isn't
exported to the modules using the MODULE_DEVICE_TABLE() macro. So the
modules autoloading won't work if the I2C device is registered using
OF or legacy board files due missing alias information in the modules.
The issue was found using Kieran Bingham's coccinelle semantic patch:

has an additional LED (LED3), this LED can be timed to be active during
