 (a): the reference count of the IIO device should be decreased.
 (b): the allocated memory should be freed with restoring the reference count.
 Therefore iio_deivce_put() is called in both cases.
 This can be handled in the last error statement.

iio: hid-sensors: Prevent crash during hot-unplug

When hid sensor hub is unplugged, there is a crash in
iio_device_unregister_trigger_consumer.
In a typical IIO driver when remove is called, it will unregister and free
trigger and then it will call iio_device_free.
The function iio_trigger_free() will free the allocated memory for trigger.
If this trigger was assigned to iio_dev->trig, then it should be set to NULL.
Othewise when iio_device_free() is called later, it finally calls
iio_device_unregsister_trigger(), which checks for
       if (indio_dev->trig)
                iio_trigger_put(indio_dev->trig);
If indio_dev->trig is not set to NULL, it calls iio_trigger_put on a bad
pointer causing crash.
This scenerio can happen in any driver, which is storing trigger pointer in
iio_dev structure and following current procedure during remove.

1) a set cleaning up and moving the ad7476 driver out of staging.
Support for a number of additional parts is also added to that driver.

2) cleanups from various people for the in kernel interface code as that
is getting more an more real use and hence people are picking up on
minor issues that made it through review.  Also a related useful set
of utility functions to avoid duplicate code for converting IIO
representations to other forms.

3) a new fractional type for our read_raw / write_raw functions.
  This allows avoiding loss of accuracy via the in kernel interfaces in some
  cases as well as being rather convenient for a lot of range -> scale
  conversions.

4) New AD5755 DAC driver.

5) Some Blackfin timer trigger improvements including hardware pulse control
for device triggering.

6) Support for the ad7091r in the ad7476 driver.

ad7091r is not really related to any of the other devices supported by this

how sampling a single channel ADC via SPI can be implemented and support for the
ad7091r can be added to the driver with just a few adjustments.

The ad7091r requires an external "conversion start" pulse to start a sample
conversion. After the conversion has finished the result can be read via SPI. We
depend on a IIO trigger to generate this signal, as a result only sampling in
buffered mode and not in manual mode is available.

Ben Hutchings [Sun, 16 Sep 2012 03:18:50 +0000 (04:18 +0100)]
staging: speakup_soft: Fix reading of init string

softsynth_read() reads a character at a time from the init string;
when it finds the null terminator it sets the initialized flag but
then repeats the last character.

Additionally, if the read() buffer is not big enough for the init
string, the next read() will start reading from the beginning again.
So the caller may never progress to reading anything else.

Replace the simple initialized flag with the current position in
the init string, carried over between calls.  Switch to reading
real data once this reaches the null terminator.

(This assumes that the length of the init string can't change, which
seems to be the case.  Really, the string and position belong together
in a per-file private struct.)
